Question 1127599: x is inversely proportional to the cube of z. What happens to x when z is halved?
I know x=K/z^3 but I do not know how to continue from there. Could you please explain what steps to take next?

x new=K/z^3new = K/(8 old/2)^3 = 8K/z old^3 = 8 x old
There must be a more simple way to explain/solve this sort of problem?
