Answer:
z = 7.5
Step-by-step explanation:
Given that z is directly proportional to x and inversely proportional to y then the equation relating them is
z = ← k is the constant of proportionality
To find k use the condition when x = 16, y = 5, z = 16, then
k = = = 5
z = ← equation of proportionality
When x = 21, y = 14, then
z = = 7.5
