=-21+12=-9

Answer 2

Ответ:

9; 5; -48; -13; 56; -7; -9.

Пошаговое объяснение:

1) (-120+93):(-3) = (-27):(-3) = 9

2) (-140+105):(-7) = (-35):(-7) = 5

3) (17-13*5) = 17-65 = -48

4) -21+56:7 = -21 + 8 = -13

5) -28+12*7 = -28 + 84 = 56

6) 10-85:5 =10 - 17 = -7

7) -21+84:7 = -21 + 12 = -9

Answer 3

Let's solve the expressions step by step:

1. (-120 + 93) / (-3): Simplifying the numerator: -120 + 93 = -27 Dividing by -3: -27 / -3 = 9 Therefore, (-120 + 93) / (-3) = 9.

2. (-140 + 105) / (-7): Simplifying the numerator: -140 + 105 = -35 Dividing by -7: -35 / -7 = 5 Therefore, (-140 + 105) / (-7) = 5.

3. 17 - 13 * 5: Multiplying 13 and 5: 13 * 5 = 65 Subtracting from 17: 17 - 65 = -48 Therefore, 17 - 13 * 5 = -48.

4. -21 + 56 / 7: Dividing 56 by 7: 56 / 7 = 8 Adding -21 and 8: -21 + 8 = -13 Therefore, -21 + 56 / 7 = -13.

5. -28 + 12 * 7: Multiplying 12 and 7: 12 * 7 = 84 Adding -28 and 84: -28 + 84 = 56 Therefore, -28 + 12 * 7 = 56.

6. 10 - 85 / 5: Dividing 85 by 5: 85 / 5 = 17 Subtracting from 10: 10 - 17 = -7 Therefore, 10 - 85 / 5 = -7.

7. -21 + 84 / 7: Dividing 84 by 7: 84 / 7 = 12 Adding -21 and 12: -21 + 12 = -9 Therefore, -21 + 84 / 7 = -9.

To summarize: (-120 + 93) / (-3) = 9 (-140 + 105) / (-7) = 5 17 - 13 * 5 = -48 -21 + 56 / 7 = -13 -28 + 12 * 7 = 56 10 - 85 / 5 = -7 -21 + 84 / 7 = -9
