2)-13,4

3)-6

4)-4,2

5)-30

Answer 2

Let's solve each of these expressions step by step:

1. -15 + (-5) = -15 - 5 = -20
2. -10 + (-3.4) = -10 - 3.4 = -13.4
3. -2.7 + (-3.3) = -2.7 - 3.3 = -6
4. -1.4 + (-2.8) = -1.4 - 2.8 = -4.2
5. -4.8 + (-4.8) = -4.8 - 4.8 = -9.6
6. -26.4 + (-3.6) = -26.4 - 3.6 = -30

So the answers are:

1. -20
2. -13.4
3. -6
4. -4.2
5. -9.6
6. -30
