−23

Answer 1

To solve this expression, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and finally addition and subtraction (from left to right).

1. First, we multiply -2 and 15:
(-2) × (15) = -30.

2. Next, we divide -30 by 23:
-30 ÷ 23 = -1.3043 (rounded to 5 decimal places).

3. Then, we multiply -1.3043 by -56:
-1.3043 × -56 = 73.0128 (rounded to 4 decimal places).

4. Finally, we divide 73.0128 by 34:
73.0128 ÷ 34 = 2.1471 (rounded to 4 decimal places).

Therefore, the answer is approximately 2.1471, which is closest to the option "23" (Start Fraction 2 over 3 End Fraction). However, none of the given options match the correct answer.
