Question

When y = 35, x=2 1/2. If the value of y directly with x what is the value of y when the value of x is 3 1/4?

Answer 1

Value of `y` is `45.5`

Explanation:

`y prop x or y=k*x; k` is variation constant

`y=35 ; x= 2 1/2 or x= 5/2 or x=2.5:. 35=k*2.5` or

`k= 35/2.5 =14 :. y=14*x` is the variation equation.

`x=3 1/4 or x =3.25 :. y =14*3.25 or y=45.5`

Value of `y` is `45.5` [Ans]
