Writing:
How can you use the addition and subtraction properties of inequality to produce equivalent inequalities?
Question 13
13.
Reasoning:
What can you do to the first inequality in each pair in order to get the second inequality?
Address each of the three pairs of inequalities, by name, in your response.
Question 14
