Answer:
Please read the answer below.
Explanation:
Let's add the two expressions as they are written in the question:
- - 4.25r + 3 and 2.5r - 6 = 4.25r + 3 + 2.5r - 6
= 6.75r - 3
In case it wasn't written accurately and the expressions are (first on the left with just one negative sign):
- 4.25r +3 and 2.5r- 6 = - 4.25r + 3 + 2.5r - 6
= -1.75r - 3
