Inverse Proportion

When the temperture stays the same, the volume of a gas is inversely proportional to the pressure of the gas. If a balloon is filled with 70 cubic inches of gas at a pressure of 14 pounds per square inch, find the new pressure of the of gas if the volume is decreased to 14 cubic inches.

y is directly proportional to x and inversely prooportional to the square of z. y=40 when x=80 and z=4. find y when x=7 and z=16.
