Try another version of this question Suppose that `y` is directly proportional to `x` . Write your answer as a decimal. `k =`
`y =`
1) Find the constant of proportionality,` ` ` k`, if `y = 46.2` when `x = 6` .
2) Using the `k` from above write the variation equation in terms of `x` .
`y =`
2) Using the `k` from above find `y` given that `x = 30` . Write your answer as a decimal.
If needed, round to the nearest tenth. 7.7
`7.7 x`
