## Algebra: A Combined Approach (4th Edition)

$\frac{1}{4}$
We are asked to evaluate the given expression when $x=-5$, $y=4$, and $t=10$. We can plug in the given variables directly to evaluate. $\frac{|x-(-10)|}{2t}=\frac{|(-5)-(-10)|}{2(10)}=\frac{|-5+10|}{2\times10}=\frac{|5|}{20}=\frac{5}{20}=\frac{5\div5}{20\div5}=\frac{1}{4}$
