HW # 30- NO HOMEWORK- HALLOWEEN Warm up You are hosting a Halloween party. You will need to provide 3 cans of soda per person, 4 slices of pizza per person, and 37 party favors. You have a total of 79 items. How many people are coming to your party? Week 8, Day Three

Warm Up Response This situation has several pieces of information: soda cans, slices of pizza, and party favors. Translate this into an algebraic equation. 3p + 4p + 37 = 79 This equation requires three steps to solve. In general, to solve any equation you should follow this procedure. Procedure to Solve Equations: 1. Remove any parentheses by using the Distributive Property or the Multiplication Property of Equality. 2. Simplify each side of the equation by combining like terms. 3. Isolate the ax term. Use the Addition Property of Equality to get the variable on one side of the equal sign and the numerical values on the other. 4. Isolate the variable. Use the Multiplication Property of Equality to get the variable alone on one side of the equation. 5. Check your solution. Example 1: Determine the number of party-goers in the opening example. Solution: 3p + 4p + 37 = 79 Combine like terms: 7p+37=79. Apply the Addition Property of Equality: 7p+37-37= Simplify: 7p=42. Apply the Multiplication Property of Equality: 7p \div 7=42 \div 7. The solution is p=6. There are six people coming to the party.
