Answer 1

Ответ:

1) (18х + 45у) :9 = 9 × (2х+5у) : 9 = 2х +5у

2) 7 ( 5m + 6n) :7 = 5m + 6n

3) 5 (8t + 11n) :5 = 8t+11n

4) 13 (15a+5b) :13= 15a+5b

Answer 2

1. (18x + 45y) : 9 = (18x / 9) + (45y / 9) = 2x + 5y
2. (35m + 42n) : 7 = (35m / 7) + (42n / 7) = 5m + 6n
3. (40t + 55n) : 5 = (40t / 5) + (55n / 5) = 8t + 11n
4. (195a + 65b) : 13 = (195a / 13) + (65b / 13) = 15a + 5b
