Question

y varies inversely as x. When x=10, y=20. Find y when x=50

Answer 1

Answer:

y=100

Step-by-step explanation:

You can solve this by comparing the ratio.

The first set is 10:20 or 1:2 when simplified.

This can then be applied to the second set. If x=50, then 50 times 2 will give you the answer of 100.
