1 Algebra 1 CCSS- 1 Standards: A.CED.1 Students will learn to solve equations, create linear equations in one variable, and use them to solve problems. Section: HW Side notes: Essential Question: What properties are used to solve equations? How do I solve one step equations? Essential Question: To solve equations we must the variable by using the properties of equality. You can do this by performing. Those are operations that each other. Adding and are inverse operations. Multiplying and are also inverse operations. Def--- Addition Property of Equality-- Adding the number to sides of an equation produces an equivalent equation. Algebraic Example For any real number a, b, and, c. Numeric Example Def--- Subtraction Property of Equality-- Subtracting the number to sides of an equation produces an equivalent equation. Algebra Example For any real number a, b, and, c. Numeric Example Examples. Solve.
2 Def--- Multiplication Property of Equality-- Multiplying sides of an equation by the number produces an equivalent equation. Algebra Example Numeric Example For any real number a, b, and, c. Def--- Division Property of Equality-- Dividing sides of an equation by the number produces an equivalent equation. Algebra Example Numeric Example For any real number a, b, and, c, such that c = 0. Examples. Solve
3 Define a variable and write an equation for the situation. Then solve. DOK 2 You have a shoe rack that can hold 25 pairs of shoes. You can still fit 8 more pairs of shoes on the rack before it is full. How many shoes are on the shoe rack? A wildlife expert estimates that in a certain year the number of male fawns born will be about the number of adult female deer. Suppose 1131 male fawns are born. About how many female deer are there? To solve an equation you must the variable using the and performing operations that each other. The addition property of equality says that the same number to both sides produces an equation. The subtraction property of equality says that the same number on both sides produces an equation. The multiplication property of equality says that the same number on both sides produces an equation. The division property of equality says that the same number on both sides produces an equation.

Section: HW Essential Question: How do I solve Two-Step Equations? Essential Question: To solve two-step equations we must still the variable. We must identify each of the operations and undo them by performing. Side notes: Examples. Solve each equation. DOK 2 Solve each equation. Justify each step.
5 Define the variable, write an equation and solve. DOK 2 Suppose you are helping to prepare a large meal. You can peel 4 potatoes per minute. You need a total of 80 potatoes. How long will it take you to finish if you have already peeled 16 potatoes? Bowling at Tustin Lanes cost Danny and Maria $12. This include both their shoe rentals at $1 each. How much did each game cast if they bowled a total 5 games? To solve two- step equations we must still (get it by itself). However, now we must identify the operation and undo them by performing to do so. To define a variable in a word problem at what they are. That is what you define the variable as.

8 Algebra 1 CCSS- 1 Standards: A.REI.3, A.CED.1, A.REI.1 Students will learn to solve equations with variables on both sides, create linear equations in one variable, and use them to solve problems. Section: HW Essential Question: How do I solve equations with variables on both sides? Essential Question: To solve equations with variables on both sides we must first of the equation, if possible. Then move the variable to only and solve like before. Examples. Solve. Side notes:
9 Define the variable, write an equation, then solve. DOK 2 A computer company, company A, charges $10 per month plus $7 per minute for access to its information. Company B charges $20 per month plus $5 per minute. For what number of minutes will the charges be the same if you use Company A or Company B?

Section: HW Side notes: Essential Question: How do we solve equations by clearing fractions and decimals from them? Essential Question: To solve equations by clearing fractions you must find the. Then multiply the to, and solve by the variable. Examples. Solve.
11 To clear decimals from an equation you must find the number of after the decimal point of all the terms across the equation. If the greatest number of decimal places is 1, multiply sides of the eq. by If the greatest number of decimal places is 2, multiply sides of the eq. by If the greatest number of decimal places is 3, multiply sides of the eq. by And so on. DOK 2 Define the variable, write an equation, then solve Your dad rented a moving truck for $59.95 plus $.25 per mile. Before returning the truck he filled up the gas tank, which cost $ The total cost of the truck was $ Find the number of miles the truck was driven.
