5.1 = 0.5 = 5:5= 3 Реши уравнения: 8. x = 40 + 15:3 = 56-35:7= 8.5+5.5 = 7.5-45:5= 45: x = 5 16+24: 8 = (16+24):8 = 5.9-7- 5.(9-7) = x: 5=3

Ответ:

1. 5 ⋅ 1 = 5

2. 0 ⋅ 5 = 0

3. 5 : 5 = 1

4. 4 + 15 : 3 = 4 + 5 = 9

5. 5 ⋅ 6 - 35 : 7 = 30 - 5 = 25

6. 8 ⋅ 5 + 5 ⋅ 5 = 40 + 25 = 65

7. 7 ⋅ 5 - 45 : 5 = 35 - 9 = 26

8. 16 + 24 : 8 = 16 + 3 = 19

9. (16 + 24) : 8 = 40 : 8 = 5

10. 5 ⋅ 9 - 7 = 45 - 7 = 38

11. 5 ⋅ (9 - 7) = 5 ⋅ 2 = 10

12. Решим уравнения:

    1. 8 ⋅ x = 40

       x = 40 : 8

       x = 5

    2. 45 : x = 5

       x = 45 : 5

       x = 9

    3. x : 5 = 3

       x = 3 ⋅ 5

       x = 15
