4.4
Step-by-step explanation:
X is inversely proportional to y, so x = k/y where k is just a constant.
X is directly proportional to z squared, so x = kz^2 where k is a constant
Here, The second relationship doesn't even matter.
Plug the values for x and y into the first equation and solve for k.
5.5=k/4
k=5.5*4
k=22
Now plug k and the second y back in.
x=22/5
x=4.4
