Since Jane wants to buys some lollipops, Jane has $13 dollars.
To answer the question, we need to solve simultaneous equations
What are simultaneous equations?Simultaneous equations are pairs of equations that contain two unknowns
How to calculate how much Jane has using simultaneous equationsLet
x = price per lollipop and y = total amount Jane hasWe know that If she buys 2 lollipops, she will have 3 dollars left, so we have that
y - 2x = 3 (1)
Also, If she wants to buy 3 lollipops, she will need 2 more dollars. So, we have that
y + 2 = 3x (2)
The required simultaneous equationsSo, the required simultaneous equations are
y - 2x = 3 (1)
y + 2 = 3x (2)
From (1), x = (y - 3)/2
Substituting x into (2), we have
y + 2 = 3x (2)
y + 2 = 3(y - 3)/2
2(y + 2) = 3(y - 3)
2y + 4 = 3y - 9
2y - 3y = -9 - 4
-y = -13
y = -13/-1
y = 13
So, Jane has $13 dollars.

a chemical company makes two brands of antifreeze the first brand is 20% pure antifreeze and the second brand is 45% pure antifreeze in order to obtain 70 gallons of the mixture that contains 30% antifreeze how many gallons of each brand of antifreeze must be used
Answer:
first brand: 42 gallons
second brand: 28 gallons
Step-by-step explanation:
So you know that the first brand is 20% antifreeze, this means that if you have x gallons then 0.20x is pure antifreeze. The same thing can be applied for the second brand except the coefficient is 0.45 and I'll just say the variable is y. If you haven't noticed, the coefficients are simply the percentages of antifreeze, but in decimal form. Anyways, since it's asking for a mixture that's 30% antifreeze and is 70 gallons that means 0.30(70) gallons is pure antifreeze. This simplifies to 21 gallons. So if we take the pure antifreeze of both mixtures we get the following equation:
[tex]21 = 0.2x + 0.45y[/tex]
the x represents how many gallons of the first brand, and the y represents how many gallons of the second brand. Since that's what it represents we also get the equation:
[tex]70=x+y[/tex]
In this equation there aren't any coefficients, since x and y represent the whole amount. the 0.2x and 0.45 simply represent how much is pure antifreeze.
So to solve this systems of equation we can solve for y or x, either works, and then substitute it into the other equation. So in this example I'll solve for y
Original equation:
[tex]70=x+y[/tex]
Subtract x from both sides
[tex]70-x=y[/tex]
So now we can substitute this into the pure antifreeze question
[tex]21 = 0.2x + 0.45y \implies21=0.2x+0.45(70-x)[/tex]
So now we can solve for x since it's the only variable in this equation
[tex]21=0.2x+31.5-0.45x[/tex]
Simplify
[tex]21=-0.25x+31.5[/tex]
Subtract 31.5 from both sides
[tex]-10.5=-0.25x[/tex]
Now divide both sides by -0.25
[tex]42=x[/tex]
So this means we have to use 42 gallons of the first brand, now we can substitute this into either equation to solve for y, but it's much easier to use the total gallon equation:
[tex]x+y=70\implies 42+y=70[/tex]
Subtract 42 from both sides
[tex]y=28[/tex]
So this means we need to use 42 gallons of the first brand and 28 gallons of the second brand

The endpoints of FG are F(3.75,9) and G (2,-12).
If point E divides FG in the ratio 3:4, the coordinates of point E are what?
If point H divides FE in the ratio 2:3, the coordinates of point H are what?
Using proportions, it is found that:
The coordinates of point E are (3,0).The coordinates of point H are (3.45, 5.4).What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Point E divides FG in the ratio 3:4, hence:
[tex]E - F = \frac{3}{7}(G - F)[/tex]
This is used to find both the x and y coordinates.
For the x-coordinate, we have that:
[tex]E - F = \frac{3}{7}(G - F)[/tex]
[tex]x - 3.75 = \frac{3}{7}(2 - 3.75)[/tex]
x - 3.75 = -0.75.
x = 3.
For the y-coordinate:
[tex]E - F = \frac{3}{7}(G - F)[/tex]
[tex]y - 9 = \frac{3}{7}(-12 - 9)[/tex]
y - 9 = -9
y = 0.
The coordinates of point E are (3,0).
Point H divides FE in the ratio 2:3, hence:
[tex]H - F = \frac{2}{5}(E - F)[/tex]
This is used to find both the x and y coordinates.
For the x-coordinate, we have that:
[tex]H - F = \frac{2}{5}(E - F)[/tex]
[tex]x - 3.75 = \frac{2}{5}(3 - 3.75)[/tex]
x - 3.75 = -0.3.
x = 3.45.
For the y-coordinate, we have that:
[tex]H - F = \frac{2}{5}(E - F)[/tex]
[tex]y - 9 = \frac{2}{5}(0 - 9)[/tex]
y - 9 = -3.6
y = 5.4.

What is the median for the set of data?
(A) 85
(B) 89
(C) 87
(D) 98
Answer:
87
Step-by-step explanation:
The median of a data set is the value that is exactly in the middle of all other values.
To find the median of a data set, we typically list the values in order of greatest to least, and we look for the number in the middle.
Here, the list-maker has already provided the list in this order!
78, 78, 83, 85, 89, 91, 95, 98
we can see two numbers exactly in the middle here--when this happens, we take the mean/average of the two:
85 + 89 = 174
174 / 2 = 87
So, the median of this data set is 87

How many sandwiches do
you think would be supplied by this
market if the price were $3.50?
=========================================================
Explanation:
Start at $3.50 on the vertical y axis. Draw a horizontal line until you reach the supply curve. Then drop straight down to land somewhere between 650 and 700 units supplied per day. Check out the diagram below.
A good estimate may be to use the midpoint. Add up those values and divide in half.
(650+700)/2 = 1350/2 = 675
Therefore, we estimate that 675 sandwiches per day would be supplied if the price was $3.50 per sandwich.
Miss Goh bought 6 blouses, 2 skirts and 2 dresses for $560. A blouse and a skirt cost $107. A blouse and a dress cost $134. What was the cost of a dress?
Answer:
$95 FOR A DRESS
Step-by-step explanation:
Let's rearrange the given:
She bought a blouse and skirt for two, a blouse and a dress for two, and a blouse for two.
A blouse and a skirt cost $107
A blouse and a dress cost $134
blouse cost x dollars
The equation:
2($107) + 2($134) + 2x = $560
SOLUTION:
$214 + $268 + 2x = $560
2x = $560 - $214 - $268
2x = $78
x = $39 for a single blouse
FIND THE COST OF DRESS:
A blouse and a dress cost $134 - $39 for a single blouse
$134 - $39 = $95
$95 IS THE COST OF DRESS

35. For the following exercises, given each set of information, find a linear equation satisfying the conditions, if possible.
35. Passes through (-2, 8) and (4, 6)
Answer:
The linear equation for the line which passes through the points given as (-2,8) and $(4,6), is written in the point-slope form as [tex]$y=-\frac{1}{3} x-\frac{26}{3}$[/tex].
Step-by-step explanation:
A condition is given that a line passes through the points whose coordinates are (-2,8) and (4,6).
It is asked to find the linear equation which satisfies the given condition.
Step 1 of 3
Determine the slope of the line.
The points through which the line passes are given as (-2,8) and (4,6). Next, the formula for the slope is given as,
[tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]
Substitute [tex]$6 \& 8$[/tex] for [tex]$y_{2}$[/tex] and [tex]$y_{1}$[/tex] respectively, and 4&-2 for [tex]$x_{2}$[/tex] and [tex]$x_{1}$[/tex] respectively in the above formula. Then simplify to get the slope as follows, [tex]$m=\frac{6-8}{4-(-2)}$[/tex]
[tex]$$\begin{aligned}&m=\frac{-2}{6} \\&m=-\frac{1}{3}\end{aligned}$$[/tex]
Step 2 of 3
Write the linear equation in point-slope form.
A linear equation in point slope form is given as,
[tex]$y-y_{1}=m\left(x-x_{1}\right)$[/tex]
Substitute [tex]$-\frac{1}{3}$[/tex] for m,-2 for [tex]$x_{1}$[/tex], and 8 for [tex]$y_{1}$[/tex] in the above equation and simplify using the distributive property as follows, [tex]y-8=-\frac{1}{3}(x-(-2))$\\ $y-8=-\frac{1}{3}(x+2)$\\ $y-8=-\frac{1}{3} x-\frac{2}{3}$[/tex]
Step 3 of 3
Simplify the equation further.
Add 8 on each side of the equation [tex]$y-8=-\frac{1}{3} x-\frac{2}{3}$[/tex], and simplify as follows, [tex]$y-8+8=-\frac{1}{3} x-\frac{2}{3}+8$[/tex]
[tex]$y=-\frac{1}{3} x-\frac{2+24}{3}$$\\ $$y=-\frac{1}{3} x-\frac{26}{3}$$[/tex]
This is the required linear equation.

You must go 45 miles per hour to reach the longest distance.
Number of hours the car can runThe given parameters are:
Speed = 60 miles per hourTime = 5 hoursWhen the speed increases by 1 mile per hour, the time reduces by 10 minutes.
This means that:
When
Speed = (60 + x) miles per hour
The time is:
Time = 5 hours - 10 minutes * x
Convert minutes to hour
Time = 5 hours - 1/6 * x hour
This gives
Time = 5 - x/6 hour
Hence, the car can run for (5 - x/6) hours
The distance for 1 tank of gasWe have:
Speed = (60 + x) miles per hour Time = (5 - x/6) hoursThe distance is calculated using
Distance = Speed * Time
This gives
Distance = (60 + x)(5 - x/6)
Expand
Distance = 300 - 10x + 5x - x^2/6
Evaluate the like terms
Distance = 300 - 5x - x^2/6
Hence, the distance for 1 tank of gas is 300 - 5x - x^2/6 miles
The longest distanceWe have:
D = 300 - 5x - x^2/6
Differentiate
D' = -5 - x/3
Set to 0
-x/3 = 5
Solve for x
x = -15
Substitute x = -15 in D = 300 - 5x - x^2/6
D = 300 - 5(-15) - (-15)^2/6
Evaluate
D = 337.5
Hence, the longest distance is 337.5 miles
The speed for the longest distanceWe have:
x = -15
Substitute x = -15 in Time = (5 - x/6) hours
Time = (5 + 15/6) hours
Evaluate
Time = 7.5 hours
The speed is calculated as:
Speed = Distance/Time
This gives
Speed = 337.5/7.5
Evaluate
Speed = 45
Hence, you must go 45 miles per hour to reach the longest distance.

[tex]3x^{2} -15x+8x-40=0[/tex]
3x(x-5)+8(x-5)=0
(3x+8)(x-5)=0
3x+8=0
x=-8/3
x-5=0
x=5
We should neglect x=-8/3 because side cannot be negative. So we have taken x=5.
Put x=5 in 3x-7 to get length
length=3(5)-7
=15-7
=8
Hence the length will be 8 cm and breadth will be 5 cm.

A fence is to be built to enclose a rectangular area of 200 square feet. The fence along three sides is to be made of material that costs 3 dollars per foot, and the material for the fourth side costs 12 dollars per foot. Find the dimensions of the enclosure that is most economical to construct.
y = 220/ ((10/3) * √22)
It is given that area is 200 square feet. Cost is 3 dollar per foot. Fourth side costs 12 dollars per foot.
This f(x,y) needs to represent the cost of the fence so we can look at each side's price. We can choose the fourth side to be along the x axis and be represented by 13x. The other sides therefore must be represented by 5y, 5y, and 5x.
So, our cost, f(x,y) = 13x + 5x + 5y + 5y = 18x + 10y
Our constraint is xy = 220 as defined by the area of a rectangle.
We can then take our constraint to be put in terms of exclusively x, giving us y = 220/x
Plugging this into our cost, the thing we are minimizing, we get f(x) = 18x + 2200/x
In order to find the minimum we use the first derivative test, taking f'(x) and finding the critical points.
f'(x) = 18 - 2200/x2
Setting this equation to be equal to 0 we find that x = ±√2200/18 . But the negative answer doesn't make sense because distance cannot be negative so we throw it out.
x = (10/3) * √22
We must verify that this is a minimum by confirming the following:
If x < (10/3) * √22, f'(x) < 0. So, f(x) is decreasing when x < (10/3) * √22.
If x > (10/3) * √22, f'(x) > 0. So, f(x) is increasing when x > (10/3) * √22.
Thus, we have guaranteed that (10/3) * √22 is the x dimension. Now we plug in this value in our original equation to find y and that is our y dimension. So, y = 220/ ((10/3) * √22)
