2-1: Writing Equations Essential Skills: Translate sentences into equations Translate equations into sentences 2-1: Writing Equations Example 1A: Sentences into Equations TTranslate the following into an equation AA number b divided by three is equal to six less than c TThe equation is b / 3 = c 6 b / 3 = c 6 Example 1B: Sentences into Equations TTranslate the following into an equation FFifteen more than x times six is y times two minus eleven TThe equation is 15 + x 6 = y 2 = 2 +x6 y 11 1) Translate the following into an equation A number c multiplied by six is two more than d 1.6c = d c = d c = d c = 6(d + 2) 2) Translate the following into an equation: Three less than a number a divided by four is seven more than three times b a 3 = 3b 2-1: Writing Equations Example 3: Write a formula TTranslate the sentence into a formula. TThe perimeter of a square equals four times the length of a side WWords: Perimeter equals four times the length of a side VVariables: Let P = perimeter and s = length of a side FFormula: Perimeter equals four times the length of a side TThe formula is P = 4s P =4s Translate the sentence into a formula: The area of a circle equals the product of and the square of the radius 1. A = + r 2 2. A = r 2 3. A = 2r 4. A = 2r + 2-1: Writing Equations Example 4A: Equations into Sentences TTranslate the following into a verbal sentence 112 2x = -5 12 2x =-5 AAnswer: Twelve minus two times x equals negative five Twelve minus two times x equalsnegative five 2-1: Writing Equations Example 4B: Equations into Sentences TTranslate the following into a verbal sentence aa 2 + 3b = c / 6 a 2 + 3b = c / 6 AAnswer: a squared plus three times b equals c divided by 6 a squared plusthree times b equalsc divided by 6 Translate the equation into a verbal sentence 12 / b 4 = Twelve minus four divided by b is negative one 2. Twelve less than four divided by b equals negative one 3. Four minus twelve divided by b equals negative one 4. Twelve divided by b minus four equals negative one Translate the equation into a verbal sentence 5a = b Five plus a equals b squared plus one 2. Five times a equals twice b plus one 3. Five times a equals b squared plus one 4. The quotient of five and a equals b squared plus one Participant Scores 5Sara Bath 5David Farrell 5Gabriel Gipli 5Caitlyn MacDonnell 5Kelliann Seedes 2-1: Writing Equations Assignment Page 77 78 Problems 1 17 (skip #9) 21 29 (skip #25) Odd problems Participant Scores 0Participant 1 0Participant 2 0Participant 3 0Participant 4 0Participant 5
