Suppose x is directly proportional to y, but inversely proportional to z. If x=3 when y=6 and z=4, then what is z when y=3?

Not enough info here....to see why

x = k * y / z

3 = k * (6) / 4

12 = 6k

2 = k

So we know that

x = 2 * 3 / z

x = 6 / z

But we need to also know the value of x to find z

Thank you! Its okay I got 8 though and it was right?

I think so... CPhill beat me to it :(

Nice try though cal!

Hehe thanks :D
