37. Реши уравнения. 48:x=92:46 x: 10 = 600 + 60 y.7=28-2

1) 48 ∶ x = 92 ∶ 46

48 ∶ x = 2

x = 48 ∶ 2

x = 24

Проверка:

48 ∶ 24 = 92 ∶ 46

2 = 2

2) x ∶ 10 = 600 + 60

x ∶ 10 = 660

x = 660 × 10

x = 6600

Проверка:

6600 ∶ 10 = 600 + 60

660 = 660

3) y × 7 = 28 - 2

y × 7 = 26

y = 26 ∶ 7

y = 26/7

y = 3 5/7

Проверка:

3 5/7 × 7 = 28 - 2

26 = 26

Ответ: 1) х = 24; 2) х = 6600; 3) y = 3 5/7
