Answer 1

Пошаговое объяснение:

1) x = 35,88 ÷ 7,5 = 4,784

2) x = 35 ÷ 3₁ = 11,67

4) x = 35 ÷ 3₁ = 11,67

7) x = 9,4 × 3,05 = 28,82

10) x = 27/7/2 × (12/2) = 27/7 × 2/12 = 1/14

12) x = 40 ÷ 1,25 = 32

1 5) x = 72 ÷ 4 = 18

11) x = 3.31 × 12 ÷ 4 × 13 ÷ 39 = 4.14

3) x = 5 ÷ 7 1/3 = 5 ÷ (22/3) = 5 × 3/22 = 0,682

6) x = 8 - (160' ÷ 13) - 9 - 46 = 8 - 160 ÷ 13 - 9 - 46 = 8 - 12.31 - 9 - 46 = -59.31

8) x = 315,9 ÷ 7,02 = 44,93

9) x = 14 3 23 4 5 26 × 10² = 14 3 23 4 5 26 × 100 = 143,234,526

12) x = 2,64 ÷ (37 - (-2)) = 2,64 ÷ (37 + 2) = 2,64 ÷ 39 = 0,068
