Question

Y=7 x=2 what is the value of x when y=21

Answer 1

Answer:

y=4.98

Explanation:

First, find the constant of proportionality , k.

y=kx
21=7k
k=3

We now start over and solve for y using the new value of x and the obtained value of k.

y=(3)(1.66)
y=4.98

Answer 2

The value of x would 6. Y divided by x would get you 3.5, therefore 21 divides by 3.5 is 6.
