Because they are the same equation, just rewritten in a different way.
s = 4p
divide both sides by 4 to get the other equation:
(1/4)s = p
They ate 3/8 of the pie because 1/4=2/8 .and 1/8+2/8=3/8. Hope this helps
Answer:
h = 8
Let the unknown number be h for height
V = LWH
984 = 20.5 x 6 x h
984 = 20.5 x 6h
984 = 123h
984 ÷ 123h
= 8
The formula for f(x) in y + 6 = 5(x - 4) in terms of x is f(x) = 5(x - 4) - 6
