Yvaries inversely as x, and y = 50 when x = 10. what is the value ofy when x = 20?
100

25

Step-by-step explanation:

Since y varies inversely with x, the relation between y and x will be:

Introducing the proportionality constant, we can write:

Using the first set of given values of x and y, we get:

This means, the relation between y and x is:

We have to find y if x = 20. Using this value in above equation, we get:

Thus y would be 25 if x is 20.
