We need to find the value of the expression:


(x+4)/(10-x)

when x = 5.

In order to do so, we can replace x with 5 in the expression above. We obtain:


(5+4)/(10-5)=(9)/(5)

This is the value written as a fraction. We can divide 9 by 5 to obtain the number:


(9)/(5)=1.8

We can also write it as a mixed number:


(9)/(5)=(5+4)/(5)=(5)/(5)+(4)/(5)=1+(4)/(5)=1(4)/(5)

Answer:


\begin{equation*} 1(4)/(5) \end{equation*}
