Answer 1

Ответ:

- 4.8 - 3.7 - 2.9 × 8.7 - 2.6 × 5.3 + 6.2 - 1.9 =

Разложим на действия:

1. -4.8 - 3.7= - (4.8 + 3.7) = -8,5
2. 2.9 × 8.7 = 25,23
3. 2.6 × 5.3 = 13,78
4. -8.5 - 25.23= - (8.5 + 25.23) = -33,73
5. -33.73 - 13.78= - (33.73 + 13.78) = -47,51
6. -47.51 + 6.2= - (47.51 - 6.2) = -41,31
7. -41.31 - 1.9= - (41.31 + 1.9) = -43,21

Ответ: -43,21

Answer 2

Let's break down the expression step by step:

1. Start with the subtraction: -4.8 - 3.7 = -8.5.
2. Then, multiply by 2.9: -8.5 * 2.9 = -24.65.
3. Next, multiply by 8.7: -24.65 * 8.7 = -214.755.
4. Subtract 2.6: -214.755 - 2.6 = -217.355.
5. Multiply by 5.3: -217.355 * 5.3 = -1150.8915.
6. Add 6.2: -1150.8915 + 6.2 = -1144.6915.
7. Finally, subtract 1.9: -1144.6915 - 1.9 ≈ -1146.5915.

So, the result of the expression is approximately -1146.5915.
