Absolute Value Inequality. I checked my list of problems from this year, looking to see what topic I hadn't posted yet. There are many, but I have settled on posting an absolute value inequality this week. Just keeping things mixed-up. I find that this topic isn't too bad.
When working with students who are learning this topic, I notice that the most common mistake they make is only solving one inequality to get their final answer. Students get frustrated when points are lost and ask why, if the answer is right. I gently remind them that the answer is right but it's also incomplete. "You're missing the second answer." If a student remembers the method for solving absolute value inequalities, then they can most often make a mistake in the solving...especially if not comfortable with fractions.
To solve this week's problem in completion, you need to recall the following math skills:
✔️ How to add/subtract fractions
✔️ The definition of absolute value and how to apply it
✔️ How to solve linear inequalities
WMP! #31 wants us to...
Check back on Friday, December 11th for the solution, which will be posted below ⬇️.
