Answer:
-55x=100
Step-by-step explanation:
5x-5(4x-8x)=100
5x-20x-40x=100
-55x=100
Answer:
the answer is C. 12.5
Step-by-step explanation:
its 12.5 because 60 min = 10 mile
and then 15 + 60 = 75 and a quarter of 60 is 15 which a quarter of 10 is 2.5 which you than add up to get 12.5
Answer:
Length = 18 in
Width = 15 in
Step-by-step explanation:
We have that the area of a rectangle is:
A = L * W
but L = 1.2 * W
A = 1.2 * (W ^ 2)
1.2 * (W ^ 2) = 270
(W ^ 2) = 270 / 1.2
W ^ 2 = 225
Therefore, W is equal to:
W = 225 ^ (1/2)
W = +/- 15, but only +15 makes sense
W = 15
Now for L:
L = 1.2 * 15
L = 18
A = 15 * 18 = 270 in ^ 2
