answer:
To solve the given expression, let's break it down step by step:
1. Start with the innermost parentheses:
-9 - 6 = -15
3 - 3 × 4 = 3 - 12 = -9
32 - 8 × 9 = 32 - 72 = -40
-5 × (-1 + 7) = -5 × 6 = -30
2. Now, substitute these values back into the expression:
60 / -15 - 54 / -9 + (-40) / -30
3. Simplify each division operation:
60 / -15 = -4
54 / -9 = -6
-40 / -30 = 4/3 or 1.33 (rounded to two decimal places)
4. Substitute the simplified values back into the expression:
-4 - 6 + 1.33
5. Perform the remaining addition and subtraction:
-4 - 6 + 1.33 = -9.67
Therefore, the value of the given expression is approximately -9.67.
