What could you use to quickly find out how much money you would earn for different hours of work? For example, sum, addition, more than, and plus all mean to add numbers together. Definition: To evaluate means to follow the verbs in the math sentence. To begin to evaluate a mathematical expression, you must first substitute a number for the variable. Solution: Evaluate means to follow the directions, which is to take 7 times y and subtract 11. When we have canceled all common factors, we have a fraction in its simplest form.

Example: What variables would be choices for the following situations? The following is a real-life example that shows the importance of evaluating a mathematical variable. Example 2: Cans of tomato sauce come in three sizes: 8 ounces, 16 ounces, and 32 ounces. $1.29 ounce ' 32 Arranging the rational numbers in ascending order: 0.0403125, 0.061875, 0.07375 Example 3: Which is greater | or |?

Example: To prevent major accidents or injuries, these horses must be fenced in a rectangular pasture. The costs for each size are $0.59, $0.99, and $1.29, respectively. Solution: Begin by creating a common denominator for these two fractions. 7 X 9 = 63, therefore the common denominator is 63.

When you are familiar with all of the problem-solving strategies, it is up to you to choose the methods that you are most comfortable with and that make sense to you. Set up an equation, draw a diagram, make a chart, or construct a table as a start to begin your problem-solving plan. Step 4: Check and Interpret: Check to see if you have used all your information. Solve Real- World Problems Using a Plan Example 1: Jeff is 10 years old. How old will Jeff be when he is twice as old as Ben? How many ears of corn will his crew harvest per hour? It will take 20 hours to harvest the entire field, so we need to divide 198,000 by 20 to get the number of ears picked per hour. Suppose Matthew's crew takes 36 hours to harvest the field. • Improper fractions are rational numbers where the numerator is greater than the denominator. A frog is sitting perfectly on top of number 7 on a number line. 93 Multi-Step Equations by Combining Like Terms In the last lesson, you learned the definition of like terms and how to combine such terms. This situation has several pieces of information: soda cans, slices of pizza, and party favors. 3p 4p 37 = 79 This equation requires three steps to solve. Use the Addition Property of Equality to get the variable on one side of the equal sign and the numerical values on the other. Apply the Addition Property of Equality: 7p 37 - 37 = 79 - 37. Apply the Multiplication Property of Equality: 7p 4- 7 = 42 -f 7. This lesson will show you how to use the Distributive Property to solve multi-step equations. Solution: Apply the Distributive Property: l Ox 18 = 78. Note that there is not always a match between the number of the practice exercise in the video and the number of the practice exercise listed in the following exercise set. " While this may seem weird to you, it is a true statement. 3x 2 -4y 2 x 4 Evaluate the expression: — — — ~[ x for x = -2, y 1. Note that there is not always a match between the number of the practice exercise in the video and the number of the practice exercise listed in the following exercise set. (3 7) -=-(7-12) 4 2-(3 (2-l)) (0 ~x 4 ' 4-(6 2) ^ °J 5. In this book, we will often use more than one method to solve a problem. You could draw a picture (it may take a while), write an equation, look for a pattern, or make a table. We need to figure out how many ears of corn are in the field. 198,000 20 9,900 The crew can harvest 9,900 ears per hour. Improper fractions can be rewritten as a mixed number - an integer plus a proper fraction. The frog jumps randomly to the left or right, but always jumps a distance of exactly 2. Evaluate the following expression: |d 7a 2 ; use a = (-1), d = 24. The length of a rectangle is one more inch than its width. We will use the following situation to further demonstrate solving equations involving like terms. You will need to provide 3 cans of soda per person, 4 slices of pizza per person, and 37 party favors. In general, to solve any equation you should follow this procedure. Remove any parentheses by using the Distributive Property or the Multiplication Property of Equality. Simplify each side of the equation by combining like terms. Apply the Addition Property of Equality: 10* 18 - 18 = 78 - 18. Apply the Multiplication Property of Equality: l Ox -f 10 = 60 4- 10. However, the practice exercise is the same in both.
