Answer 1

Ответ:

Пошаговое объяснение:

1) -2.1 - 0.4 - 7.9 - 4.6 = -15

2) -8.3 - 4.5 - 1.7 - 5.5 = -20

3) -37 - 22 - 13 = -72

4) 42 - 45 - 12 = -15

Answer 2

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

1. -2.1 + (-0.4) + (-7.9) + (-4.6)

   = -2.1 - 0.4 - 7.9 - 4.6

   = -2.1 - 0.4 - 7.9 - 4.6

   = -14.0

2. -8.3 + (-4.5) + (-1.7) + (-5.5)

   = -8.3 - 4.5 - 1.7 - 5.5

   = -20.0

3. -37 + (-22) + (-13)

   = -37 - 22 - 13

   = -72

4. 42 + (-45) + (-12)

   = 42 - 45 - 12

   = -15

So, the simplified expressions are:

1. -14.0
2. -20.0
3. -72
4. -15
