Question

The variables x and y vary directly. Use the values to find the constant of proportionality, k. Then write an equation that relates x and y. Write any fractions in simplest form.

y=20; x=12

Answer 1

x= 6/5y

Explanation:

x =ky

x=12,y=20

12 =20k

divide both sides by 20

k=12/20

= 6/5

X=6/5y
