Essential Question Check-In

Question 7. How do you solve a two-step inequality? Answer: First, isolate the variable. On one side of the inequality we put the variable, and on other side we put what’s left. If the variable is multiplied by some number, we have to divide inequality by that number. If we divide or multiply by a negative number, we have to reverse the direction of inequality.

c. Describe the solution set of the compound inequality x < 2 and x > 7. Answer: The solution set is the intersection of sets where x is greater than 2 and less than 7, x ε (2, 7).

d. Describe the solution set of the compound inequality x > 2 or x < 7. Answer: The solution set is the union of sets where x is less than 2 and greater than 7, x ε (-∞, 2) ∪ (7, ∞).

Go Math Lesson 8.4 7th Grade Solving Two-Step Inequalities Question 22. Communicate Mathematical Ideas Joseph used the problem-solving strategy Work Backward to solve the inequality 2n+ 5 < 13. Shawnee solved the inequality using the algebraic method you used in this lesson. Compare the two methods. Answer: Working backward consists of mentally performing the following operations: Subtract 5 from 13 to obtain 8 and dividing by 2 gives us that n must be less than 4. Let’s perform the algebraic operations: 2n + 5 < 13 Write the inequality 2n + 5 – 5 < 13 – 5 Subtract 5 from both sides 2n < 8 Simplify \(\frac{2 n}{2}\) < \(\frac{8}{2}\) Divide both sides by 2 n < 4 Simplify The two methods are basically the same. Working backward consists of mostly working mentally, while the algebraic method is mostly written, but the operations performed are the same. The two methods are basically the same. The backward method works mentally while the algebraic method is a written solution.
