Question

(0.2а + 0.5б)+(0.8а - 11 б)

Answer 1

0,2а+0,5б+0,8а-11б

а-10,5б

Answer 2

To simplify the expression, you can combine like terms:

(0.2a + 0.5b) + (0.8a - 11b)

Combine the "a" terms: 0.2a + 0.8a = 1a (since 0.2a + 0.8a = 1a or a)

Combine the "b" terms: 0.5b - 11b = -10.5b (since 0.5b - 11b = -10.5b)

Now, the simplified expression is:

1a - 10.5b

You can also write it as:

a - 10.5b
