Question

-(3,4а+2,5в-2)+(0,3в-0,7а)-3(3,1-5)+27,5

Answer 1

Ответ:

2.7а-2.2в+35.2

Пошаговое объяснение:

3.4а-2.5в+2+0.3в-0.7а+5.7+27.5=

=2.7а-2.2в+35.2

Answer 2

Let's simplify the expression step by step:

1. Start by distributing the negative sign in front of the parentheses: -(3,4а + 2,5в - 2) = -3,4а - 2,5в + 2

2. Next, perform the operations inside the parentheses: (0,3в - 0,7а) = 0,3в - 0,7а

3. Continue with the rest of the expression: -3(3,1 - 5) = -3 * (-1,9) = 5,7

4. Now, put all the simplified terms together: -3,4а - 2,5в + 2 + 0,3в - 0,7а + 5,7

5. Combine like terms (terms with the same variable): (-3.4a - 0.7a) + (-2.5v + 0.3v) + 2 + 5.7

6. Calculate the values of the combined terms: -4.1a - 2.2v + 7.7

So, the simplified expression is: -4.1a - 2.2v + 7.7
