Final answer:
The compound inequality that involves < and > when solving absolute value inequalities is x > 5 or x < -5.
Step-by-step explanation:
The compound inequality that involves < and > when solving absolute value inequalities is option b. x > 5 or x < -5.
When solving absolute value inequalities, we consider two cases: when the expression inside the absolute value is positive and when it is negative. In the case of x > 5, the expression inside the absolute value is positive, and in the case of x < -5, the expression inside the absolute value is negative.
Therefore, the correct compound inequality is x > 5 or x < -5.
