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:
D. 5/6
Step-by-step explanation:
There are 30 marbles
If you add the black, red, and green marbles together, you get 25
25/30 is equivalent to 5/6
Again, decimals and fractions represent all the values in between integers. Decimals are simply one step more of simplification from fractions.
