Answers:
Ally gets 100 poundsBarry gets 150 poundsCat gets 250 pounds=====================================================
Work Shown:
x = some positive real number
2x = amount Ally gets
3x = amount Barry gets
5x = amount Cat gets
Note that the ratio 2x:3x:5x reduces to 2:3:5 after dividing all parts by x.
Add up the parts and you should get a sum of 500 pounds. Solve for x.
2x+3x+5x = 500
10x = 500
x = 500/10
x = 50
Based on that x value, we then can say:
2x = 2*50 = 100 pounds is what Ally gets3x = 3*50 = 150 pounds is what Barry gets5x = 5*50 = 250 pounds is what Cat getsAs a check, 100+150+250 = 500.
Also, note that the ratio 100:150:250 fully reduces to 2:3:5 after dividing all parts by the GCF 50.
Those two facts help confirm our answers.

3y > 2x + 12
2x + y< -5
Answer:
The vertices of both where they cross show (-4,1)
Step-by-step explanation:
3y > 2x + 12
x < 3(y - 4) / 2
y > 2 (x + 6) / 2
2x + y< -5
= x> -5
set = together
x < 3(y - 4) / 2 shows dotted ascending line attached through x=-6
This means x=--6 y = 0
x>-5 shows boundary dotted vertical line through -5
this means x = -5 y = 0
If it had been x ≥ -5 it would have been solid boundary line.
The area within the dotted lines create a right angle triangle where the far left angle shows ascends to (-6, 0) and crosses y at 0,4 however the shaded area will not got hat far and stop at -4,0 and the area below.
As seen attached when both are plotted with dash dotted boundary lines.
The vertices of both show (-5,1)
How to solve this? I don’t get it how it is x=3 where she solve this ?
Step-by-step explanation:
Given the logarithmic expression:
[tex]3log_{5}2 + log_{5}x = log_{5}24[/tex]
Using the Logarithmic Product Rule:
[tex]log_{a}x + log_{a}y = log_{a}(xy)[/tex]
And the Logartihmic Power Rule:
[tex]log_{a}x^{y} = ylog_{a}x[/tex]
Rewriting your given logarithmic expression by applying the power rule:
[tex]log_{5}2^{3} + log_{5}x = log_{5}24[/tex]
I will use the following logarithmic property to cancel out the logarithmic expressions, which will show why x = 3.
[tex]_{b}log_{b}x = x[/tex]
Raise each logarithmic expression by the same value as the base, 5:
[tex](_{5}log_{5}2^{3} ) + (_{5}log_{5}x )= (_{5}log_{5}24)[/tex]
2³(x) = 24 (2³ is multiplied with x instead of addition because of the Product Rule).
Now that you're left with just 2³(x) = 24, it's easy to see why the answer is x = 3:
2³(x) = 24
8x = 24
Divide both sides by 8:
8x/8 = 24/8
x = 3

using the graph, determine the coordinates of the roots of the parabola
Answer:
(-1, 4)
Step-by-step explanation:
Use of the coordinate plane.
The vertex of the parabola is 1 to the left and up 4.
Think of the vertex as where the curve starts.
Answer:
-3 and 1
Step-by-step explanation:
Hello!
The roots of the parabola are the intersections of the graph and the x-axis (y = 0).
Since the graph's vertex is above the x-axis and opens down, the graph has two roots.
The points of intersection are:
[tex](-3,0)[/tex][tex](1,0)[/tex]Therefore, the roots of the parabola are -3 and 1.

what is the answer to 4x=8
Answer:
2
Step-by-step explanation:
You spin the spinner and flip a coin. Find the probability of the compound event.
A spinner is divided into 5 equal regions. The sections are labeled 1, 2, 3, 4, and 5.
The probability of spinning a prime number and not flipping heads is
.
3/10
2, 3, and 4 are prime numbers. Those are three numbers worth. The maximum number on the spinner is 5 so you multiply 5 by 2 and get 10. Again, 3 numbers are prime numbers. So from there you add 3 and 10 as a fraction and get 3/10

How much simple interest does $4,678.00 earn in 529 days at a rate of 7.3%? Round to the nearest cent.
Answer:
$5,172.93
Step-by-step explanation:
We're gonna use the simple interest formula: P = A(1 + r(t))
P = final amount
A = starting amount (4,678)
r = rate (0.073)
t = years (529/365)
P = 4,678(1 + 0.073(529/365))
P = 5,172.9324

5. Which point lies on the line: y - 4 = -3(x + 2)?
Answer:
(- 2, 4 )
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
y - 4 = - 3(x + 2) ← is in point- slope form
with (a, b ) = (- 2, 4 )

B) y = -2x + 4
C) y = -4x - 2
D) y = -2x - 4
Answer: Solution In Photo
Answer:
D) y = -2x - 4Step-by-step explanation:
Use the points:
(-2, 0) and (0, -4)The y- intercept is - 4 and the slope is:
m = (-4 - 0)/(0 - (-2)) = -2The line is:
y = -2x - 4Correct choice is D
The angles of a quadrilaterals are x⁰, (x-10)⁰, (x+30)⁰ and ( 2x)⁰, then the greater angle is
Answer:
136°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the given angles and equate to 360
x + x - 10 + x + 30 + 2x = 360 , simplify left side
5x + 20 = 360 ( subtract 20 from both sides )
5x = 340 ( divide both sides by 5 )
x = 68
Then
largest angle = 2x = 2 × 68 = 136°

Step-by-step explanation:
the midpoint is(4,1)
that is the answer
Answer:
(4, 1 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = P (6, 6 ) and (x₂, y₂ ) = Q (2, - 4 ) , then
midpoint = ( [tex]\frac{6+2}{2}[/tex] , [tex]\frac{6-4}{2}[/tex] ) = ( [tex]\frac{8}{2}[/tex] , [tex]\frac{2}{2}[/tex] ) = (4 , 1 )
Diane is going to rent a truck for one day. There are two companies she can choose from, and they have
Company A charges $74 and allows unlimited mileage.
Company B has an initial fee of $65 and charges an additional $0.60 for every mile driven.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
>
ISO
DO
Х
Answer:
Step-by-step explanation:
Company A Total Cost: Ca = $74
Company B Total Cost: Cb = $65+$0.60m, where m is the miles driven.
We want to find for what values of m with Company A charge less than Company B:
Ca < Cb ?
$74 < $65 + $0.60m
$9 < $0.60m
15 < m
m > 15 miles
Company A will cost less than Company B when less than 15 miles are driven. The costs are the same for 15 miles and higher for Company B beyond 15 miles.
i need help! do i subtract the 45-64? or add!?
Answer:
19°
Step-by-step explanation:
180-64=116
116+45=161
180-161=19
Answer:
B) 19
Step-by-step explanation:
find the other angle of W first.
to do that, take 180 - 64
that makes angle W 116
add angle W and angle Y
116 +45 = 161
take 180 - your answer
180 - 161 = 19
