Answer:
see explanation
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 5 , x = 21
k = yx = 5 × 21 = 105
y = 
← equation of variation
When x = 10, then
y = 
= 10.5
Simplify: 64/72 = 8/9
