How Will This Worksheet on "Solve Compound Inequalities" Benefit Your Students' Learning?

  • It enhances problem-solving skills as students need to use different mathematical methods to solve the inequality.
  • It strengthens logical reasoning skills as you learn how different math statements are connected by words like "and" or "or".
  • It improves proficiency of different algebraic concepts such as inequalities, solving equations, and representing solutions visually on a number line.
  • It fosters critical thinking as students assess multiple conditions and use appropriate steps to make decisions.
  • It provides a strong base for handling more complex math topics such as systems of inequalities, linear programming, and calculus.

How to Solve Compound Inequalities?

  • For inequalities connected by “or”, solve both the inequalities separately.
  • Combine the two results to write a compound inequality.
  • For inequalities connected by “and”, identify the operation to be used to isolate the variable.
  • Simplify the inequality.

Solved Example

Q. Solve for gg. \newlineg20>4g - 20 > -4 or g+193g + 19 \leq 3\newlineWrite your answer as a compound inequality with integers.\newlineChoices:\newline(A) 16g1616 \geq g \geq -16\newline(B) g>16g > 16 or g16g \leq -16\newline(C) 16>g1616 > g \geq -16\newline(D) g16g \geq 16 or g16g \leq -16
Solution:
  1. Isolate gg in first part: Solve the first part of the compound inequality g20>4g - 20 > -4. To isolate gg, we need to add 2020 to both sides of the inequality. \newlineg20+20>4+20g - 20 + 20 > -4 + 20 g>16g > 16
  2. Isolate gg in second part: Solve the second part of the compound inequality g+193g + 19 \leq 3. To isolate gg, we need to subtract 1919 from both sides of the inequality. \newlineg+1919319g + 19 - 19 \leq 3 - 19 g16g \leq -16
  3. Combine solutions: Combine the solutions from Step 11 and Step 22 to write the final compound inequality.\newlineThe solution is g>16g > 16 or g16g \leq -16.

About Worksheet

Algebra 1
One-Variable Inequalities

Solving compound inequalities refers to solving inequalities that have two or more inequalities in them. These inequalities are a combination of two or more inequalities linked by the words “and” or “or”. In this process, we solve for the value of the variable that fits the inequality by using inverse operations but with more than one condition at a time. In these worksheets, students will solve the inequalities linked by “and” or “or”.

For example: Solve `–4>v–17≥–11` for `v`.

Write your answer as a compound inequality with integers.

Choices: `[[13 > v > 6][v > 13 or v ≤ 6][13 > v ≥ 6][v > 13 or v < 6]]`
