Ответ:

161,78

Пошаговое объяснение:

64,5 + ( 6,7 ∙ 15 - 3,22 )  =  64,5 + (100,5 - 3,22)  =  64,5 + 97,28 = 161,78

Answer 3

To solve the expression:

64.5 + (6.7 * 15 - 3.22)

Follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), Addition and Subtraction (left-to-right).

1. First, perform the calculation inside the parentheses:

6.7 * 15 = 100.5

2. Now, subtract 3.22 from the result:

100.5 - 3.22 = 97.28

3. Finally, add this result to 64.5:

64.5 + 97.28 = 161.78

So, the answer is 161.78.
