To find the value of the expression, substitute the given values into the expression and simplify:
![\begin{aligned}xy&+z\\(5)(0)&+(5)/(8)\end{aligned}](https://img.qammunity.org/2023/formulas/mathematics/high-school/fh2wtzuviok4leaetcm9rrssu85r9q2rzv.png)
Since anything multiplied by zero equals zero, we can simplify:
![\displaystyle0+(5)/(8)](https://img.qammunity.org/2023/formulas/mathematics/high-school/2x50l5aph30cg9uy68c17qp7l1lnhsfys6.png)
Finally, adding zero to any value has no effect, so we can remove the first term entirely:
