Question

The variable z is inversely proportional to x when x is 3 z has the value 1.6666666666667. What is the value of z when x =12 ?? Help please ASAP

Answer 1

The governing equation is z = k/x.

When x=3, z = 1 2/3, or z = 5/3. Find k: 5/3 = k/3. Then k = 5, and the

governing equation becomes z = 5/x.

Now if x=12,

z = 5/12 (answer)
