3. Lesson 19: Rearranging Formulas Page 104

4. 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

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

6. 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)?

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