Answer 2

Let's solve these two equations step by step:

1. -23.4 + (-9) When you add a negative number to another negative number, you can think of it as subtracting the absolute values of the numbers and keeping the sign of the larger number. In this case: |-23.4| = 23.4 |-9| = 9 Since 23.4 is larger than 9, the result will be negative, and the sign will be the same as the larger number (which is negative). So: -23.4 + (-9) = -23.4 - 9 = -32.4

2. -23.4 + 9 When you add a negative number to a positive number, you can think of it as subtracting the absolute values of the numbers and keeping the sign of the larger number. In this case: |-23.4| = 23.4 |9| = 9 Since 23.4 is larger than 9, the result will be positive, and the sign will be the same as the larger number (which is negative). So: -23.4 + 9 = -23.4 - 9 = -14.4

So, the solutions are: -23.4 + (-9) = -32.4 -23.4 + 9 = -14.4
