Answer 1

1)

(12m-5m)×4=252

12m-5m]7m

7m×4=28

28m×4=252

Answer 2

Пошаговое объяснение:

Номер 110

1).

$(12m - 5m) \times 4 = 252$

$7m \times 4 = 252$

$7m = 63$

$m = 63 \div 7$

$m = 9$

2).

$(4n + 3n) \times 11 = 154$

$7n = 14$

$n = 14 \div 7$

$n = 2$

3).

$45 \div (4m - m) = 3$

$45 \div 3m = 3$

$9m = 45$

$m = 45 \div 9$

$m = 5$

4).

$(19n - 6n) \div 4 = 26$

$13n \div 4 = 26$

$13n = 104$

$n = 104 \div 13$

$n = 8$

5).

$(16m + 5m) \div 18 = 7$

$21m \div 18 = 7$

$21m = 126$

$m = 126 \div 21$

$m = 6$

6).

$(17n - 8n) \times 13 = 351$

$9n = 27$

$n = 27 \div 9$

$n = 3$
