Y is inversely proportional to X.

When y

20, x = 2

Work out y when x = 5

When x = 5, y = 8.

Step-by-step explanation:

y is inversely proportional to X.

This means that we solve this using the rule of three for inversely proportional variables, that is, we apply line multiplication instead of cross multiplication.

y = 20, x = 2

Work out y when x = 5

20 - 2

x - 5

Applying line multiplication

When x = 5, y = 8.
