Question

No4 Выполни деление: 1) (18х + 45y) : 9: 2) (40m +55n) : 5; 3) (195а + 65b) : 13; 4) (117m - 39n) : 13; 5) (136а - 85b) : 17; 6) (128c - 72d) : 8.

Answer 1

Ответ:

(18х/9) + (45у/9) = 2х + 5у

(40m/5) + (55n/5) = 8m + 11n

(195a/13) + (65b/13) = 15a + 5b

(117m/13) - (39n/13) = 9m - 3n

(136a/17) - (85b/17) = 8a - 5b

(128c/8) - (72d/8) = 16c - 9d
