Answer:
z = 
Step-by-step explanation:
Given 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 x = 7, y = 7 and z = 2
k = 
= 
= 2
z = 
← equation of proportionality
When x = 10 and y = 12, then
z = 
= 
=
