Question

50 POINTS! The variables x and y have a proportional relationship, and y=2/5 when x=5/8

Which equation represents this relationship?
y= 1 9/19x y=16/25x y= 9/40x y= 1/4x

Answer 1

`y=(16)/(25) x`

Explanation:

If y = 2/5 and x = 5/8

`y / x=(2)/(5) /(5)/(8)= (2)/(5) * (8)/(5) =(16)/(25)`

So
`(y)/(x) =(16)/(25)\\` ⇒
`y =(16)/(25)x`
