Question

What is the k, the constant of proportionality for this question​

Answer 1

k = 0.90

Explanation:

y = 18 ; x = 20 ; k = ?

y = k * x

18 = k * 20

k = 18/20

k = 9/10

k = .90

The constant of proportionality basically states that there is a value that will multiply the value of x and make the mathematical statement valid. Hope this helps!
