  1. Lesson 1.7 Translate verbal phrases to number form. Objective: Key phrases: Addition: The sum of five and a number 5 + x x + 6 Six more than a number x + 5 A number plus five x + 4 A number increased by four Subtraction: n - 7 The difference of a number and 7 n - 6 Six less than a number 3 - n Three minus a number Two less a number 2 - n A number decreased by 8 n - 8

  2. Key Phrases: Multiplication: The product of a number x and 6 6x A number n multiplied by 3 3n Ten times a number c 10c Division: A number h divided by 7 The quotient of 9 and a number n Vocabulary: Mathematical model – The expression,equation,inequality that represents the problem in number form. Verbal model – The word form of the problem.

  3. Equations and Inequalities: Mathematical sentence is a math problem with an equal/inequality symbol. Equation - A math problem with an equal symbol. Is –Means Equals Inequality has more than one solution and uses one of the following inequality symbols: > means greater than < means less than > means greater than or equal to < Means less than or equal to Examples: Five plus six is less than y 5 + 6 < y A number decreased by 6 is greater than or equal to the sum of a number and 10 x – 6 > x + 10

  4. Practice Problems: Translate the following 1. Eleven decreased by four times a number 11 – 4x 2. A number increased by ten is twenty-four x + 10 = 24 3. Twenty–six is the sum of a number and fifteen 26 = x + 15 4. A number is the product of six and eight x = 6(8)

  5. Examples: 6 + 4x six plus a number times 4 16 - n the difference of sixteen and a number five times a number, decreased by eight 5x - 8 a number decreased by the sum of 10 and 5 x – (10 + 5) Practice Problems: Directions: Write the mathematical model for each problem. 1. eight plus a number 8 + x m – 10 2. the difference of a number and 10 3. nine less a number times four 9 – 4z 6c + 4 4. six times a number, increased by four
