Question

2)-6-(+8,1);-5-(+6,7);8-(+9,5);​

Answer 1

1)-6-8.1=-14.1

2)-5-6.7=-11.7

3)8-9.5=-1.5

Answer 2

To evaluate the given expressions, we'll perform the subtraction operation indicated by the minus sign (-) and the addition operation indicated by the plus sign (+). We'll start by simplifying each expression step by step:

1. -6 - (+8,1): Since we have a positive number within parentheses, we can simply remove the parentheses and change the sign of the number inside: -6 - 8.1 = -14.1

2. -5 - (+6,7): Again, we'll remove the parentheses and change the sign of the number inside: -5 - 6.7 = -11.7

3. 8 - (+9,5): Removing the parentheses and changing the sign of the number inside: 8 - 9.5 = -1.5

Therefore, the simplified expressions are: -6 - (+8,1) = -14.1 -5 - (+6,7) = -11.7 8 - (+9,5) = -1.5
