Answer:
z=12
Step-by-step explanation:
It is given that x varies jointly as y and z, it means



where, k is the constant of proportionality.
It is given that x=8 when y=4 and z=9


Divide both sides by 36.


The value of k is 2/9.

We need to find the value of z when x=16 and y=6.
Substitute x=16 and y=6 in the above equation.


Multiply both sides by 3.

Divide both sides by 4.

Therefore, the value of z is 12.
