Answer 3

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

1. -9 + (-3.5): -9 + (-3.5) = -12.5

2. 0.6 + (-1/2) + 0.7: 0.6 + (-1/2) + 0.7 = 0.6 - 0.5 + 0.7 = 0.1 + 0.7 = 0.8

3. -3.8 + (-5.4): -3.8 + (-5.4) = -9.2

So, the simplified expressions are:

1. -9 + (-3.5) = -12.5
2. 0.6 + (-1/2) + 0.7 = 0.8
3. -3.8 + (-5.4) = -9.2
