LESSON 1.1 CONTINUED EXAMPLE 3 NAME _________________________________________________________ DATE ____________ Practice with Examples For use with pages 3–10 Operations with Real Numbers At rest, the average person’s heart beats 65 times per minute. During aerobic exercise, this rate increases by 40%. a. How many times does the average person’s heart beat per hour? b. How many times will the average person’s heart beat per minute during aerobic exercise? SOLUTION 65 beats 60 minutes a. beats per hour 1 minute 1 hour 3900 b. To find 40% of 65, multiply. 40% 65 0.4 65 26 Rewrite 40% as 0.4. Simplify. During aerobic exercise, the average person’s heart would beat 65 1 26 5 91 times per minute. Chapter 1 Exercises for Example 3 In Exercises 15 and 16, use the following information. At Indianapolis Motor Speedway, one lap is 2.5 miles in length. The average speed of an Indy racing car is 190 miles per hour. 15. Find the length of one lap in yards. 16. How many seconds would it take to complete one lap? Copyright © McDougal Littell Inc.

LESSON 1.2 Practice with Examples For use with pages 11–17 NAME _________________________________________________________ DATE ____________ GOAL Evaluate algebraic expressions and simplify algebraic expressions by combining like terms VOCABULARY Chapter 1 A variable is a letter that is used to represent one or more numbers. An algebraic expression is an expression involving variables. Like terms are expressions that have the same variable part. Constant terms such as 4 and 2 are also like terms. The base of an exponent is the number or variable that is used as a factor in repeated multiplication. For example, in the expression 4 b , 4 is the base. An exponent is the number or variable that represents the number of times the base is used as a factor. For example, in the expression 4 b , b is the exponent. A power is the result of repeated multiplication. For example, in the expression 4 2 16, 16 is the second power of 4. Any number used to replace a variable is a value of the variable. When the variables in an algebraic expression are replaced by numbers, the result is called the value of the expression. Terms are the parts that are added in an expression, such as 5 and x in the expression 5 x. A coefficient is the number multiplied by a variable in a term. Two algebraic expressions are equivalent if they have the same value for all values of their variable(s). EXAMPLE 1 Using Order of Operations 23 18 3 2 7 23 18 9 7 23 2 7 22 4 Evaluate the power. Divide. Add within parentheses. Multiply.
