Question

Can someone just check if im doing this right... Write an equation that expresses the following: w varies jointly with u and d and inversely with p. Use k as the constant of proportionality.

I came up with w=k(ud/p)

Is that right?

Answer 1

You are correct

saying "w varies jointly with u and d " means

w = k*(ud)

and saying "w varies...inversely with p" means

w = k/p

put them together to get what you have

\[\large w = k\frac{ud}{p}\]

Answer 2

yay!! thx @jim_thompson5910 :)
