Answer 2

Ответ:

-15+(-10)= -15-10= -25

-8+(-2,6)= -8-2,6= -10,6

-2,8+(-6,2)= -2,8-6,2= -9

-4,9+(-1,3) = -4,9-1,3= -6,2

-2,6+(-2,6) = -2,6-2,6= -5,2

-19,2+(-27,8) = -19,2-27,8= -47.

Answer 3

Let's solve each of these addition problems step by step:

1. -15 + (-10) = -25

2. -8 + (-2.6) = -10.6

3. -2.8 + (-6.2) = -9.0

4. -4.9 + (-1.3) = -6.2

5. -2.6 + (-2.6) = -5.2

6. -19.2 + (-27.8) = -47.0

So, the results are:

1. -25
2. -10.6
3. -9.0
4. -6.2
5. -5.2
6. -47.0
