Answer 1

Ответ:

-7

Пошаговое объяснение:

1)-3,9*2,8=-10,92

2)-10,92+26,6=15,68

3)15,68:(-3,2)=-4,9

4)-4,9-2,1=-7

Answer 2

Let's break down the expression step by step:

1. Start with the multiplication: -3 * (9 * 2.8 + 26.6)

2. Perform the addition inside the parentheses: -3 * (25.2 + 26.6)

3. Continue with the addition: -3 * 51.8

4. Now, multiply -3 by 51.8: -155.4

5. Finally, divide the result by -3.2: -155.4 / -3.2

Now, let's calculate the final result:

-155.4 / -3.2 ≈ 48.5625

So, (-3,9×2,8+26,6)÷(-3,2)-2,1 is approximately equal to 48.5625.
