Question

г)0,2(3a - 1) + 0,3 - 0,6a;
д) 0,9 (2b - 1) - 0,5b + 1;
e) -2,6(5 - c) - с + 8 ​

Answer 1

Объяснение:

г)

$0.2(3a - 1) + 0.3 - 0.6a = 0.6a - 0.2 + 0.3 - 0.6a = 0.6a + 0.1 - 0.6a = 0.1$

д)

$0.9(2b - 1) - 0.5b + 1 = 1.8b - 0.9 - 0.5b + 1 = 1.3b - 0.9 + 1 = 1.3b + 0.1$

е)

$- 2.6(5 - c) - c + 8 = - 13 + 2.6c - c + 8 = - 13 + 1.6c + 8 = - 5 + 1.6c$
