y is inversely proportional to X.

When y

20, x = 2

Work out y when x = 5

Sagot :

Answer:

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

[tex]5y = 40[/tex]

[tex]y = \frac{40}{5}[/tex]

[tex]y = 8[/tex]

When x = 5, y = 8.
