8-4x=2x
-4x-2x=-8
-6x=-8
x=-6/-8
=3/4 or 0.75
I am not sure, but I'll give you the layout.
Step-by-step explanation:
32/160= p/100
P=?
P stands for the percent
Answer:
on the third number it says 344,636 and there is a double 4
Represent your unknowns: Let s be the length of one side of the box. The relationship between s and x is s = x-4.
The volume of the box is (length)(width)(height), which here equals the following: V(x) = (x-4)*(x-4)*(x). You may either leave this result as is, or shorten it to V(x) = (x-4)^2*x, or expand (x-4)*(x-4)*(x).
$4.20, 2.73/65 >>> .042 x 100 >>> answer.
Bonus:
To check it you'd do 4.20/20, then multiply .21 by 13 (65% divided into 5% portions = 13 portions) and your answer will be $2.73.
