Answer 2

Ответ:

-15.7

Пошаговое объяснение:

6.9 + 5.8 = 12.7

-3 - 12.7 = -15.7

Answer 3

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS):

1. Start with parentheses (brackets):

   • Solve the innermost parentheses first:
     • 6.9 + 5.8 = 62.1

2. Replace the result back into the expression:

   • -3 - 62.1

3. Now perform the subtraction:

   • (-3) - 62.1 = -3 - 62.1 = -65.1

So, the result of the expression -3 - (6.9 + 5.8) is -65.1.
