Answer 2

A) To solve the expression -24:(-8)+6.5, we follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's break down the expression step by step:

1. -24:(-8) = -24 ÷ (-8) Dividing -24 by -8 gives us 3.

2. 3 + 6.5 = 9.5

Therefore, the result of -24:(-8)+6.5 is 9.5.

B) For the expression 3.5(-2)+4:(-0.2), let's break it down step by step:

1. 3.5(-2) = -7 Multiplying 3.5 by -2 gives us -7.

2. 4:(-0.2) = 4 ÷ (-0.2) Dividing 4 by -0.2 gives us -20.

3. -7 + (-20) = -27

So, the result of 3.5(-2)+4:(-0.2) is -27.

C) The expression -3.2:8-0.4 can be solved as follows:

1. -3.2 ÷ 8 = -0.4 Dividing -3.2 by 8 gives us -0.4.

2. -0.4 - 0.4 = -0.8

Therefore, the result of -3.2:8-0.4 is -0.8.
