Subtracting Negative Numbers
When Subtracting a positive number from a negative number—start at the negative number, and count backwards the additional amount you’re subtracting.
Example: Let’s say we had the problem -5 – 3. This would be read as “negative five minus three.” This can be thought of on a number line, which means we’re going to start at the negative number (-5) and keep counting back the -3, arriving at -8.

Answer:
R = 5t
Step-by-step explanation:
given s is three times t then s = 3t and
R = 3t + 2t = 5t
If a shape is translated (has it's vertex' coordinates moved/changed), then it retains its original values but just has different vertex coordinates.
Thus since DE is equal to UV, then,
DE = UV; substitution:
5=5
