Question

Y is inversely proportional to X.
When X = 3, y = 24
What is Y if x = 24?

Answer 1

y =3

Explanation:

Since y varies inversely as x , this means that

y ∝ 1/x

Removing the proportionality sign , we have

y = k/x , where k is the constant

Given;

X = 3, y = 24

Substitute the values into the equation

24 = k/3, cross multiply

24 (3) = k

k = 72.

Substitute k into the equation, the equation becomes;

y = 72/x

to find y when x is 24 Substitute it into the formula;

y = 72/24

y = 3
