Lesson 19: Rearranging Formulas Page 104

STUDENT OUTCOME The student will…. learn to think of some of the letters in a formula as constants in order to define a relationship between two or more quantities, where one is in terms of another, for example holding V in V = IR as constant, and finding R in terms of I. Homework: pgs 108 problems 1-5, 8, 9, 11-17

CLASSWORK - Exercise 1 Solve each equation for x. For part (c), remember a variable symbol, like a, b, and c represents a number.

Exercise 2 Compare your work in parts (a) through (c) above. Did you have to do anything differently to solve for x in part (c)?

Exercise 3 Solve the equation ax − b = c for a. The variable symbols x, b, and c represent numbers.

Example 1: Rearranging Familiar Formulas p.105

Exercise 4

Exercise 5 pg 106 Rearrange each formula to solve for the specified variable. Assume no variable is equal to 0.

Example 2: Comparing Equations with One Variable to those with more than One Variable pg. 107

Example 2 continued...

CLOSING How is rearranging formulas the same as solving equations that contain a single variable symbol? How is rearranging formulas different from solving equations that contain a single variable symbol?
