Answer:
When x = 1 and z = 4, 
Step-by-step explanation:
The variation described in the problem can be written using a constant of proportionality "b" as:

The other piece of information is that when x = 5 and z = 1, then y gives 25/9. So we use this info to find the constant "b":

Knowing this constant, we can find the value of y when x=1 and z=4 as:

Answer:
0.527
Step-by-step explanation:
Divide 6 by 27 and that will get you to a long number like 0.2222222222 but we can shorten it to 0.222. After this you will divide 11 by 36 leading you to the answer of 0.3055555556 which again will shorten to 0.305. Add both of these solutions together and you will get 0.527 as your answer!
