Question

If y varies directly as x and y = 5.5 when x = 11, find x when y = 3.5

help

Answer 1

7

Explanation:

Let us say that
`y_(1)`= 5.5,
`x_(1)`= 11, and
`y_(2)` = 3.5.

`(y_(2))/(y_(1)) =(x_(2))/(x_(1))`

`(3.5)/(5.5) =(x_(2))/(11)`

`(7)/(11) =(x_(2))/(11)`

`x_(2) =7`

I hope this is correct and helps you!
