Answer: 0.89z
Think of it like 100% - 11% = 89%
You save 11%, so you need to pay the remaining 89%
Taking 89% of z then leads to 0.89z
So that's why z - 0.11z = 0.89z
Answer:
x y
2 8
3 12
5 60
7 28
Step-by-step explanation:
5 x 12 = 60
Did you ever get the answer? I have pretty much the same exact one but mine said 150 skaters and I don't know how to answer it.
Good evening Brian,
For this problem, let's look at what we're given. So we have a pool with a length that is 13 m (meters) longer than its width, and we're given the perimeter, or distance around the entire pool, which is 74 m.
We know that the pool has a rectangular shape and that the perimeter of a rectangle is <span>width + length + width + length ⇒ 2(W) + 2(L)</span>.
Given the information provided, we can rewrite the equation to fit this problem. Since we're told that the length is equal to 13 m + the width, so we can represent the length as W +13 m. We can now rewrite the perimeter equation to be:
2(w) + 2 (w + 13 m) ⇒ 2(w) + 2(w) + 2(13 m) ⇒ 4(w) + 26 m = 74 m.
We're down to one variable now so this should be easy. Subtract 26 m from both sides,
4(w) = 48 m
Now divide each side by 4 in order to find the width.
w = 12 m
-Hope this helps!
