X, y, and z are three quantities. x varies inversely with y when z is ...
Given Information:
- x varies inversely with y when z is constant
- y varies inversely with z when x is constant
- When y = 8 and z = 7, x = 30

Calculating the constant of proportionality:
- From the given information, we can write the equation as: x = k * (1/y) when z is constant
- Substituting the values when y = 8, z = 7, and x = 30, we get: 30 = k * (1/8)
- Solving for k, we get: k = 240

Finding x when y = 16 and z = 21:
- Using the constant of proportionality k = 240, and the equation x = k * (1/y), we substitute y = 16
- x = 240 * (1/16)
- x = 15

Final Answer:
- When y = 16 and z = 21, x = 15
