3. -1,6×-7=11,2

Answer 3

To calculate the expression (-10.5 + 6.5) ÷ 2.5 * (-7), you should follow the order of operations, which is typically represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). In this case, you don't have any exponents, so you can simplify the expression step by step:

1. First, perform the addition inside the parentheses: -10.5 + 6.5 = -4.

2. Next, perform the division: -4 ÷ 2.5 = -1.6.

3. Finally, multiply the result by -7: -1.6 * (-7) = 11.2.

So, the final answer is 11.2.
