Math Question 2

Question

Suppose z varies inversely with t and that z=12 when t=7. What is the value of z when t=6?

Answer 1

Here you use the proportion z=k/t wjere K is the unknown.

1.) We plug in the variables Z and T to get (12/1)=(k/7)

2.) Cross multiply to get 84=K

3.) Perform the inverse equation to now get Z=84/T

4.) Plug in T to get Z

5.)Z=14
