Question

-5(0,3б+1,7)+12,5-8,5б

Answer 1

=-1.5в-8.5+12.5-8.5в=4-10в=2(2-5в)

Answer 2

To simplify the given expression, let's perform the operations step by step:

1. Distribute the -5 across the terms inside the parentheses: -5 * 0 = 0 -5 * 3б = -15б -5 * 1,7 = -8,5

So the expression becomes: -15б - 8,5 + 12,5 - 8,5б

2. Combine like terms: -15б - 8,5б = -23,5б -8,5 + 12,5 = 4

The simplified expression is: -23,5б + 4
