Question

39-47+(-42)-(-51)=-3×(-7)•(-5)​

Answer 1

Ответ:

39-47+(-42)-(-51)

-8-42-51=-50-51=-101

-3*(-7)*(-5)=21*(-5)=-105

Answer 2

Let's solve the equation step by step:

1. Perform the operations inside the parentheses first: -42 - (-51) = -42 + 51 = 9

2. Now we have: 39 - 47 + 9

3. Perform the addition and subtraction from left to right: 39 - 47 = -8 -8 + 9 = 1

4. Now the left-hand side of the equation becomes: 1

5. Solve the right-hand side of the equation: -3 × (-7) × (-5)

   Since the product of three negative numbers is negative: -3 × (-7) × (-5) = -3 × 35 = -105

So, the equation is: 1 = -105

The equation is not correct; there seems to be a mistake in the original statement. Please double-check the equation or provide the correct equation if there was an error.
