Answer 2

Ответ:

1. 10
2. 5,5
3. -17
4. -18.4
5. -100
6. -280

Answer 3

Let's calculate the expressions:

1. 7 - (-3) = 7 + 3 = 10
2. -3.5 - (-9) = -3.5 + 9 = 5.5
3. -9 - (+8) = -9 - 8 = -17
4. (-9.2) - (+9.2) = -9.2 - 9.2 = -18.4
5. 5/9 + (-159) = 5/9 - 159 (you can't add these two as they have different units, one is a fraction and the other is a whole number).
6. (-338) + 58 = -280

So, the results are:

1. 10
2. 5.5
3. -17
4. -18.4
5. 5/9 - 159 (unless you clarify the units, this is not directly solvable)
6. -280
