Answer:
x = 55
Step-by-step explanation:
Given that x varies inversely as y then the equation relating them is
x = [tex]\frac{k}{y}[/tex] ← k is the constant of variation
To find k use the condition x = 11 when y = 15
11= [tex]\frac{k}{15}[/tex] ( multiply both sides by 15 )
165 = k
x = [tex]\frac{165}{y}[/tex] ← equation of variation
When y = 3 , then
x = [tex]\frac{165}{3}[/tex] = 55
