Question

Evaluate the expression when x=5 and z=7.25z+ xSimplify your answer as much as possible.

Answer 1

We are given the expression

$\frac{5z+x^2}{x}$

and are asked to evaluate it when x=5 and z=7. For this, we simply replace the given values on the original expression, like this:

$\frac{5(7)+(5)^2}{5}$

And now we simplify it as much as possible:

$\frac{35+25}{5}=\frac{60}{5}=12$
