Question

Suppose that y varies directly with x
and y = 5 when x = 6. What is y
when x = 5?

Answer 1

y=25/6

Explanation:

We can set up a proportion!

We know that y/x=y/x because they vary directly.

So, we have 5/6=y/5. We need to solve for y.

We cross multiply and get:

6y=25

y=25/6

When x equals 5, y will equal 25/6.

Hope this helps
