What is the constant variation of k, of the direct variation, y=kx, through (5,8)

8/5

Step-by-step explanation:

Plug in the point given into

y=kx.

The number you get for y will be your constant of variation, also know as constant of proportionality.

(x,y)=(5,8) implies 8=k(5)

So in solving that equation we just need to divide both sides by 5 giving us:

8/5=k.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
