If y varies inversely with x, and y = 48 when x = 6, find y when x = 18.

y = 16

Step-by-step explanation:

Given that,

y varies inversely with x i.e.

Where

k is a constant of proportionality

Put y = 48 and x = 6 in the above equation to find k.

So,

Now put k = 288 and x = 18 in the above equation to find y.

So, the value of y is equal to 16 when x = 18.
