  1. Welcome Back!!! Algebra Comprehensive Today is a A-day! (I think...) January 2, 2012 HAPPY NEW YEAR!!!!

  2. Title: Solving Literal Equations/Evaluating Formula's Warm-up: Solve the following proportions: 1. 2. A car travels 125 miles in 3 hours. How far would it travel in 5 hours? Jane wants to make a doll that is a replica of a friend. The scale that she will use is 1 centimeter on the doll will represent 2 inches on her friend. Her friend’s foot measures 8.5 inches. What will be the size of the doll’s foot?

  3. Literal Equation: when the coefficients and constants have been replaced by variables. Ex.) ax + b = c Example 1: Solve the equation above for x. Then use the solution to solve 2x + 5 = 11

  4. You try! 1.) Solve the literal equation for x. Then use the solution to solve the equation. a - bx = c 12 - 5x = -3

  5. Example 2: Rewrite 3x + 2y = 8; so that y is a function of x.

  6. Example 3: The area A of a triangle is given by the formula A = ½bh where b is the base and h is the height. a.) Solve the formula for the height h. b.) Substitute 64.4 for A and 14 for b in the rewritten formula. Solve for the height.

  7. You try! 1.) Write 5x + 4y = 20 so that y is a function of x. 2.) The perimeter P of a rectangle is given by the formula P = 2L + 2w where L is the length and w is the width. a.) Solve the formula for the width w. b.) Use the rewritten formula to find the width of the rectangle shown. P = 19.2 ft. w 7.2 ft.

  8. Challenge: A pet store sells aquariums that are rectangular prisms. The volume V of an aquarium is given by the formula V=lwh where l is the length, w is the width, and h is the height. a. Solve the formula for h. b. Use the rewritten formula to find the height of an aquarium shown, which has a volume of 5850 cubic inches.

  9. Classwork: Fun with Formula's WS and Formula's in Action WS

  10. Homework: Pgs. 187-189 7, 19, 20, 26, 27, 33, 36
