Answer:
A
Step-by-step explanation:
Joint variation is given by:

Where k is some constant.
We are given that y = 360 when x = 4 and z = 10. Therefore:

Solving for k:

Therefore, our equation is:

Then when x = 5 and z = 12:

The answer is A.
They are both decimals.
But 0.04 > 0.004.
Step-by-step explanation:
STEP 1
Equation at the end of step 1
(((x3) - 22x2) + x) - 4 = 0
STEP 2
Checking for a perfect cube
2.1 x3-4x2+x-4 is not a perfect cube
<h3>Ans; x=4</h3>
