Try another version of this question Suppose that `y` is inversely proportional to `x` .
Find the constant of proportionality `k` if `y = 6` when `x = 7` .
`k =`
Using the `k` from above write the variation equation in terms of `x` .
`y =`
Using the `k` from above find `y` given that `x = 21` .
` y =`
If needed, round answer to 3 decimal places.
