Answer:
2197 cubic centimeters
Step-by-step explanation:
13^3=2197
4 people x 45 minutes = 180 minutes total to paint 5 walls
180/5 = 36 minutes of man work per wall
36 * 4 walls = 144 total minutes
144/6 people = 24 minutes total
"x", stands for a <em>variable</em>, in which any number can be placed inside. If there is an equal sign, x would stand for the number that solves the equation.
9(1 + 4x)
Simplify. Distribute 9 to both 1 and 4x
9(1) = 9, 4x(9) = 36x
36x + 9 is the same as 9(1 + 4x)
hope this helps
It's a because the form for being proportional is
ab=k
or
a/b=k
4/6=k
4 times 6=k
then 5 times 7=k
false so
so there is no ratio so the answer is A
