Question

help please2

Answer 1

Are you familiar with the cross method?

Answer 2

`y varies directly with x`

\(y \: \alpha \: x\)
so, let k be the constant of proportionality.
\(y = kx\)

^^ All that is true for all the direct variation problems.

Answer 3

so your first step will be to find the value of k from the given information.

`y =12, x =15`

use this and the equation y = kx
to get the value of k.
can you ?
