if the variable Z is inversely proportional to X, then there is a constant k such that Z=k%2FX
When X=3 , Z=6.3333333333333.
What is the value of Z when X+=+8
first use X=3 , Z=6.3333333333333 to find k
6.3333333333333=k%2F3
k=6.3333333333333%2A3
k=18.9999999999999
so, when X+=+8, we will have
Z=k%2FX
Z=18.9999999999999%2F8
Z=2.3749999999999875

Z=2.375
