Question

If y varies directly as x and y = 11 when x = 2.5, find y when x = 27.5.

Answer 1

121

Explanation:

you can either set up a proportion or a table (i inserted a picture for both ways!) After setting up a table you would calculate how much it is to get from 2.5 to 27.5 (so you divide 27.5/2.5) to get 11. Then you move to the y side of the table where you would have to multiply 11×11 to get your answer (which is 121)

Answer 2

27.5

Explanation:

y=consx

y=x

y=27.5
