To the Student

This Study Guide and Intervention Workbook gives you additional examples and problems for the concept exercises in each lesson. The exercises are designed to aid your study of mathematics by reinforcing important mathematical skills needed to succeed in the everyday world. The materials are

organized by chapter and lesson, with two Study Guide and Intervention worksheets for every lesson in

Glencoe Algebra 1.

Always keep your workbook handy. Along with your textbook, daily homework, and class notes, the completed Study Guide and Intervention Workbook can help you in reviewing for quizzes and tests.

To the Teacher

These worksheets are the same ones found in the Chapter Resource Masters for Glencoe Algebra 1. The

answers to these worksheets are available at the end of each Chapter Resource Masters booklet as well

as in your Teacher Wraparound Edition interleaf pages.

Chapter 1 4 Glencoe Algebra 1

Evaluate Algebraic Expressions Algebraic expressions may contain more than one operation. Algebraic expressions can be evaluated if the values of the variables are known. First, replace the variables with their values. Then use the order of operations to calculate the value of the resulting numerical expression.

Evaluate x

3 + 5(y - 3) if x = 2 and y = 12. x 3 + 5(y - 3) = 2 3 + 5(12 - 3) Replace x with 2 and y with 12. = 8 + 5(12 - 3) Evaluate 2 3 = 8 + 5(9) Subtract 3 from 12. = 8 + 45 Multiply 5 and 9. = 53 Add 8 and 45.

The solution is 53.

Exercises

Evaluate each expression if x = 2, y = 3, z = 4, a = 4 5 , and b = 3 5quotesdbs_dbs14.pdfusesText_20
