Using the properties of inequalities, write down the inequality that you will get if you: add the number –5; 2.7; 7; to both sides of the inequality 18>−7. subtract the number 2; 12; −5; from both sides of the inequality 5>−3. multiply both sides of the inequality −9 −6 by the number 3; −3; −1.

See below

Step-by-step explanation:

1

Add –5; 2.7; 7 to both sides

2

Subtract 2; 12; -5 from both sides

3

Multiply both sides by 3; −3; −1

When multiplying both sides of inequality by positive number the sign stays as is, when multiplying both sides of inequality by negative number the sign reverses

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
