Question

- -(1,5a+2,5b-0,5)-(4,4a-1,7b+2)

Answer 1

Ответ: -5,9a-0,8b-1,5

Пошаговое объяснение:

-1,5-2,5b+0,5-4,4a+1,7b-2=-5,9a-0,8b-1,5

Answer 2

To simplify the expression -(-(1.5a + 2.5b - 0.5) - (4.4a - 1.7b + 2)), follow these steps:

1. Distribute the negative sign inside the first set of parentheses: -(-(1.5a + 2.5b - 0.5)) = 1.5a + 2.5b - 0.5

2. Distribute the negative sign inside the second set of parentheses: -(4.4a - 1.7b + 2) = -4.4a + 1.7b - 2

Now, the expression becomes:

(1.5a + 2.5b - 0.5) - (-4.4a + 1.7b - 2)

3. Remove the outer set of parentheses and combine like terms: 1.5a + 2.5b - 0.5 + 4.4a - 1.7b + 2

4. Combine like terms by adding or subtracting coefficients of 'a' and 'b': (1.5a + 4.4a) + (2.5b - 1.7b) + (-0.5 + 2)

5. Simplify further: 5.9a + 0.8b + 1.5

So, the simplified expression is:

5.9a + 0.8b + 1.5
