Answer 1

Ответ:

=3-0,3а-3а+3=6-3,3а

ответ: 6-3,3а

Answer 2

Let's simplify the expression step by step:

1.5(2 - 0.2a) + 3(-a + 1)

First, distribute the 1.5 and 3 to the terms inside the parentheses:

(1.5 * 2 - 1.5 * 0.2a) + (3 * -a + 3 * 1)

Now, perform the multiplications:

(3 - 0.3a) + (-3a + 3)

Now, combine like terms:

(3 - 3a - 0.3a + 3)

Combine the constants (3 + 3 = 6) and the 'a' terms (-3a - 0.3a = -3.3a):

6 - 3.3a

So, the simplified expression is:

6 - 3.3a
