Let's set up an equation using w to represent the weekly allowance.
w/2 + 10 = 18
Then solve:
Subtract 10 from both sides
w/2 = 8
Multiply by two on both sides
w = 16
The answer is 16.

Let's set up another equation using c to represent the original number of candy.
(c - 3) ÷ 5 = 3
Solve:
Multiply by 5 on both sides
c - 3 = 15
Add three on both sides
c = 18
The answer is 18

Hope this helped! If you have any more questions or don't understand, please comment or DM me. :)

Madison saves 40% of all that she earns for washing cars. So far she has saved $72 . How much has she earned in all?

UkoKoshka [18]

Answer:

40% = 72

divide both sides by 40 to find 1%

1% = 1.8

now multiply by 100 to find total amount earned

100% = 180

total earned $180

Triangle ABC is being dilated with the center of dilation at the origin. The image of C, point C' has coordinates of (7.2, 3.6).

MAXImum [283]

General Idea:

When we are given a point P(x, y) centered at origin with a scale factor of k, then the dilated point will be given by P' (kx, ky)

Applying the concept:

In the diagram given, the coordinate of C is (6, 3). Triangle ABC is being dilated with the center of dilation at the origin. The image of C, point C' has coordinates of (7.2, 3.6).

If C (x, y) centered at origin with a scale factor of k, then the dilated point will be given by C' (kx, ky)

We know $x = 6$ & $kx = 7.2$
