Question

If x varies directly with y and x = 3.5 when y = 14, find x when y = 18.

Answer 1

there's definitely other ways to solve this, but I used a proportion.

Then you can make this equation:

14x = 3.5 * 18

I solved for it and got 4.5 .

Answer 2

x = 4.5

Explanation:

there's definitely other ways to solve this, but I used a proportion.

`(3.5)/(x) = (14)/(18)`

Then you can make this equation:

14x = 3.5 * 18

I solved for it and got 4.5 .
