Answer:
y = 36
Step-by-step explanation:
Given y varies directly as z and inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = - 18, z = 3 when x = 6 , then
- 18 =
( multiply both sides by 6 )
- 108 = 3k ( divide both sides by 3 )
- 36 = k
y =
← equation of variation
When x = 5 and z = - 5, then
y =
=
= 36
