A 3. On a recent shopping trip, you see a sale advertising 4 pairs of socks and 3 pairs of shoes for $90. Write an equation using to represent the cost of socks and y to represent the cost of shoes.
A)40x + 30y - 90
B)30x + 40y = 90
C)3x + 4y - 90
D)4x + 3y = 90

Answer:  Check out the diagram below.

Explanation:

Use a calculator to find that:

[tex]A = \sqrt{18} \approx 4.24\\\\B = \sqrt{73} \approx 8.54\\\\C = \sqrt{30} \approx 5.48\\\\D = \sqrt{52} \approx 7.21\\\\E = \sqrt{7} \approx 2.65\\\\[/tex]

You'll then plot those decimal approximate values on the number lines given.

For example, 4.24 will go somewhere between 4 and 5. It's closer to 4 than it is to 5. The other values are handled the same way. The placement of the points doesn't have to be perfect.

Check out the diagram below. I made one single number line and plotted all the values on it. However, you'll have 5 separate number lines (one value per number line).

Answer:

x=12

10x = 120

5x = 60

Step-by-step explanation:

paralellograms will become 360 degrees

so 2(5x) +2(10x)= 360

Simplify:

10x + 20x = 360

= 30x

divide both sides by 30 and isolate

30x = 360

30        30

x=12

multiply 12 by 10x and 5x

10x = 120

5x = 60

Answer:

The graph showing the temperature change over time is missing.

Step-by-step explanation: The slope of the line in the graph is the rate of temperature change per minute.

1. Calculate the slope between for each of the 3 ranges listed. Slope is rise/run: Take two points at the upper and lower boundaries of each range. You should have three sets of points:

e.g., (0,100) and (340, 175); (345, 176) and (360, 180); finally (360,185) and (380, 200). I made these up, since there is no graph. but the x values, the time in minutes, correspond to the ranges requested.

If the slopes are diferent, then explain that the rate of temperature rise is different for each segment.

3. Time is 360 + 60 = 420, temperature is 80: (420,80)

Answer:

52° and 52°

Step-by-step explanation:

An isosceles triangle has two base angles that are congruent. So let x be the measure of the base angle so that by Triangle Angle-Sum Theorem, we can write: X+X+76=180 and next would be 2X+76=180 and then it would be 2X=104 and finally it would be X=52. So there for the measures of the base angles are 52° and 52°. There hoped it helped!!!!

Answer:

= 50, C

Step-by-step explanation:

? = 50

This is because the 50 shown is vertically opposite to the unknown angle, which they are equal

(Vertically opposite angles can be formed between two opposing lines)

Step-by-step explanation:

to turn a fraction into a decimal you divide the top number of a fraction by the bottom one. To convert an improper fraction to a mixed fraction, divide the numerator by the denominator, write down the quotient as the whole number and the remainder as the numerator on top of the same denominator

[tex]\mathrm{Apply\:rule}:\quad \:-a\left(-b\right)=ab[/tex]

[tex]=\frac{2-\left|-\frac{2}{3}+2\cdot \frac{1}{5}\right|}{-13}[/tex]

[tex]-\frac{2}{3}+2*\frac{1}{5}=-\frac{4}{15}[/tex]

[tex]=\frac{2-\left|-\frac{4}{15}\right|}{-13}[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{-b}=-\frac{a}{b}[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{a}{b}}{c}=\frac{a}{b\cdot \:c}[/tex]

Hence, Jim can lay 125 tiles and Pete can lay 25 more so 125+25=150 tiles.

Answer from -chisnau

Answer:

y=2x-5

Step-by-step explanation:

1) Factor out the common term 3

3(2x-y)=15

2)Divide both sides by 3

2x-y=15/3

3) Simplify 15/3 to 5

2x-y=5

4) Subtract 2x from both sides

-y=5-2x

5) Multiply both sides by -1

y=-5+2x

6) regroup terms

y=2x-5

Answer:

C

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 2 ) and (x₂, y₂ ) = (2, - 4) ← 2 points on the line

m = [tex]\frac{-4-2}{2-(-2)}[/tex] = [tex]\frac{-6}{2+2}[/tex] = - [tex]\frac{6}{4}[/tex] = - [tex]\frac{3}{2}[/tex]

and using (a, b ) = (2, - 4 ) , then

y - (- 4) = - [tex]\frac{3}{2}[/tex](x - 2) , that is

y + 4 = - [tex]\frac{3}{2}[/tex] (x - 2) → C

Answer:

201

Step-by-step explanation:

As the distance from Kendal to Hereford is given 201

Answer: First you want to divide $10 from 6 tacos. You should get a number like 1.6666 continuing, the. You want to multiply the 4 tacos times the answer you got from 10/6 so your problem would look like 1.66667 x 4

You should get 6.6667 or you can sum it up with 6.67 or $6.70

Step-by-step explanation:

it's something in algebra i don't remember but basically the top number (12) has the x on the bottom which is multiplication and the bottom number (8) has addition so those tell u how ur supposed to get those numbers

so basically u need to find two numbers that add up to 8 and multiply to 12 so the factors are 6 and 2 because 6 • 2 is 12 and 6 + 2 = 8. hope this helps

Answer:

6 and 2

Step-by-step explanation:

6 x 2= 12

6 + 2= 8
