As y varies directly with x, there is a proportionality constant. As x increases by that certain constant, y also increases. We equate:
y = kx
where k = proportionality constant.
Given the condition, y = 5 when x = 4, then we solve for k:
5 = k(4)
k = 5/4 or 1.25
When y = 8, then
8 = (5/4)(x)
x = 8/(5/4) = (8)(4/5) = 32/5 or 6.4 (ANSWER)
Answer:

Step-by-step explanation:
Similar shapes with scale factor
have proportional volumes with coefficient
i.e.

where

Since

then

Hence,

You multiply five by 3.75 and you get 18.75 ft. to get yards you divide by three and you get 6.25 yards
