Question

in an equation y varies directly as x varies. if y = 55 when x = 22, what is the value of x when y = 85?​

Answer 1

x=34

Explanation:

If you put Y and X into a ratio then it will be

5:2

because since their GCF is 11, then we will have to divide both of the numbers by 11.

If y=85 then that means that it was multiplied by 17. If we want them to stay within the same ratio, then we will have to multiply X (2) by 17.

That will get you 34.
