You can put this solution on YOUR website! The variable z is directly proportional to x, and inversely proportional to y. When x is 14 and y is 19, z has the value 11.052631578947.
What is the value of z when x= 19, and y= 24
------------------
11.052631578947 = 210/19
----
z = k*x/y where k is some constant.
210/19 = k*14/19
k = 15
=====================
What is the value of z when x= 19, and y= 24?
z = 15*19/24
z = 95/8
----------------------------------
You can do it without finding the value of k, but the answer is the same.
