Elementary Algebra Practice Exam Solutions #6-8

In this lesson, the instructor provides solutions to a practice test for an online Elementary Algebra class. The solutions cover topics such as solving inequalities, finding the slope of a line, and solving for angles in a triangle using algebraic equations. The instructor walks through each problem step-by-step, explaining the reasoning behind their approach and demonstrating how to check the solution.

These are solutions to a Practice Test made for my online Elementary Algebra class.
