Question

The variable Z is directly proportional to X, and inversely proportional to Y. When X is 6 and Y is 3, Z has the value 6.

What is the value of Z when X = 10, and Y = 8



Round to at least the thousandths place if needed.

Answer 1

 

         kX

Z = -------

          Y

 

 

        k(6)

6 = --------

         3

 

 

Solve: k = 3

 

 

         kX
Z = -------
          Y

        3(10)

Z = ---------

          8

 

 

Z =  3.75

 

I think, but no one else answered it so maybe it is another question without an answer.
