For example, -8xy^5/2x^3y and 3n^2/-9n^5.

Re: Ratio problem  TOPIC_SOLVED

I guess solving with cross multiply wasn't working out for me.

So 3 sets of 4's and 3's, which means 12 yellow and 9 red.

S + 5 = S

3(S + 5) = S

3S + 15 = S
- 15 -15

3S = S - 15
-S -S

2S = -15
/2 /2

S = -7.5

[SPLIT] length of a rectangle is 3 more than twice its width  TOPIC_SOLVED

I have another problem I can't solve.
The length of a rectangle is 3 more than twice its width. The perimeter is 48 feet. Find the width.


I came up with an equation 2w + 3 + w = 48.

When I solved, W = 15. There is no choice for 15.

I tried again, and came up with 2w + 3 + 2w = 48

Solve for W = 11.25

Re: [SPLIT] length of a rectangle is 3 more than twice its width  TOPIC_SOLVED

1. W

2. 2w + 3

3. P = 2(w) + 2L

4. P = 2(w) + 2(2w + 3)

5. 2W + 4W + 3 = 48

6W + 3 = 48

48 - 3 = 45

6w = 45
/6 /6

w = 7.5
