Question

If Z is inversely propotional to x and z=5 x=7 find the value of x when z=70

Answer 1

Answer:

Step-by-step explanation:

When two numbers are inversely proportional it is defined as:

a=k/b

Where a is inversely proportional to b, and k is a constant.

Therefore, in this problem:

z=k/x

When z=5, x=7, so we can use this to find k:

5=k/7

k=35

So our equation now becomes:

z=35/x

When z=70, we have to find the value of x:

70=35/x

x=1/2
