2 Literal Equations A Literal Equation is an equation that contains two or more variables. You are ordering pizza and sandwiches. You have a budget of $80. How many sandwiches can you buy if you buy 4 pizzas? 7 MENU Pizza $ 10 Sandwich $ 5 This situation can be modeled using a Literal Equation. cost per pizza # of pizzas cost per sandwich # of sandwiches 4 pizzas 7 pizzas That was easy

3 More Literal Equations Solve each equation for y. Then find the value of y for each value of x.x. I don’t like fractions.

4 Literal Equations with Only Variables Solve each equation for x.x. Use the distributive property in reverse. So that means... Asi de Facil

5 Formulas Perimeter of a Rectangle Circumference of a Circle Area of a Rectangle Area of a Triangle Area of a Circle Distance Traveled Temperature (Celsius)

6 Working with Formulas What is the radius of a circle with circumference 64 feet? Round to the nearest tenth. A car travels on a highway at a rate of 65 mph. How long does it take for the car to travel 25 miles? Round to the nearest tenth. That was easy

7 Homework Page : 12 – 34 Even Numbers Only

8 Comparison of Regular Equations & Literal Equations Solve for x.x.Solve for r.r. Asi de Facil

9 Rewriting a Formula The following formula is used to convert degrees Fahrenheit to degrees Celsius. Rewrite the formula to convert degrees Celsius to degrees Fahrenheit. The following formula is used to calculate the Surface Area of a cylinder. Rewrite the formula to solve for h.h.

10 More Rewriting Formulas Solve each equation for the given variable. That was easy

11 Homework Page 113:

12 Page 112: 12, 14, 16 Solve each equation for y. Then find the value of y for each value of x.x.

13 Page 112: 20, 22, 24, 26 Solve each equation for x.x. That was easy Hey, that has an x on both sides!

14 Page : 28, 30, 34 Solve each equation for the appropriate variable. What is the radius of a circle with circumference 22 m? A triangle has height 4 ft and area 32 ft 2. What is the length of its base? You can use the following formula to find the batting average, A, of a batter who has h hits in n times at bat. If a batter has a batting average of.290 and has been at bat 300 times, how many hits does he have? Asi de Facil
