Answer:

Please read the answer below.

Step-by-step 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
