1 This situation can be modeled using a Literal Equation. Literal EquationsA 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 pizzas?MENUPizza $ Sandwich $5This situation can be modeled using a Literal Equation.cost per sandwich# of sandwichescost per pizza# of pizzas4 pizzas7 pizzasThat was easy
2 More Literal Equations Solve each equation for y. Then find the value of y for each value of x.I don’t like fractions.
3 Literal Equations with Only Variables Solve each equation for x.Use the distributive property in reverse.So that means...Asi de Facil
4 Formulas Perimeter of a Rectangle Circumference of a Circle Area of a RectangleArea of a TriangleArea of a CircleDistance TraveledTemperature (Celsius)
5 Working with Formulas That was easy 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 Comparison of Regular Equations & Literal Equations Solve for x.Solve for r.Asi de Facil
8 Rewriting a FormulaThe following formula is used to convert degrees Fahrenheit to degrees Celsius.The following formula is used to calculate the Surface Area of a cylinder.Rewrite the formula to convert degrees Celsius to degrees Fahrenheit.Rewrite the formula to solve for h.
9 More Rewriting Formulas Solve each equation for the given variable.That was easy
11 Page 112: 12, 14, 16Solve each equation for y. Then find the value of y for each value of x.
12 Hey, that has an x on both sides! Page 112: 20, 22, 24, 26Solve each equation for x.Hey, that has an x on both sides!That was easy
13 Solve each equation for the appropriate variable. Page : 28, 30, 34What is the radius of a circle with circumference 22 m?A triangle has height 4 ft and area 32 ft2. 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
