Answer:
y = 192
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 = 16 and z = 2 when x = 42
k =
=
= 336
y =
← equation of variation
When x = 14 and z = 8, then
y =
= 192
=52*51*50*49*48*47 divided by 1*2*3*4*5*6
