Пошаговое объяснение:1)2550:204=12,5

2)12,5-6,9=5,6

3)5,6*6,7=37,52

4)40-37,52=2,48

Answer 2

Let's break down the expression step by step:

1. 2550:204 - This is the division operation.
2. (2550:204) -6,9 - This is the result of the division subtracted by 6 and then multiplied by 9.
3. 40 - (2550:204 - 6,9) - This is 40 subtracted by the result obtained in step 2.
4. (40 - (2550:204 - 6,9)) • 6,7 - Finally, this is the result obtained in step 3 multiplied by 6,7.

Now, let's calculate the expression:

1. 2550 divided by 204 equals 12.5.
2. Subtract 6 from 12.5 and then multiply by 9: (12.5 - 6) * 9 = 6.5 * 9 = 58.5.
3. Subtract 58.5 from 40: 40 - 58.5 = -18.5.
4. Finally, multiply -18.5 by 6.7: -18.5 * 6.7 ≈ -124.45.

So, the result of the expression is approximately -124.45.
