Question 995654: Write the statement as an equation. Use k as the constant of variation.
Y is directly proportional to x and inversely proportional to the square of z.
Y=???
Suppose y= 16 when x= 3 and z= 2. Find x when y= 4 and z = 5
X=???

You can put this solution on YOUR website!
Y is directly proportional to x and inversely proportional to the square of z

Y=kx%2Fz%5E2

Use the data from the second question to find the value for k;
and then you can answer this question.
