7.4 Proportional Relationships and Percentages
In this unit, students use ratios, scale factors, unit rates (also called constants of proportionality), and proportional relationships to solve multi-step, real-world problems that involve fractions and percentages. They use long division to write fractions presented in the form \(\frac a b\) as decimals, e.g., \(\frac{11}{30} = 0.3\overline6\) . They learn to understand and use the terms “repeating decimal,” “terminating decimal,” “percent increase,” “percent decrease,” “percent error,” and “measurement error.” They represent amounts and corresponding percent rates with double number line diagrams and tables. They use these terms and representations in reasoning about situations involving sales taxes, tips, markdowns, markups, sales commissions, interest, depreciation, and scaling a picture. Students use equations to represent proportional relationships in which the constant of proportionality arises from a percentage, e.g., relationship between price paid and amount of sales tax paid.

Circle any given values that make the inequality true. (Example 3)
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.

Solve each inequality. Graph and check the solution.
Texas Go Math Grade 7 Lesson 8.4 H.O.T. Focus On Higher Order Thinking Answer Key
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.
