18. Table of Contents Date: 9/7 Section: 2-1 Title: Variables and Expressions Page-2-3

19. a. Variable Variable – A variable is a letter or symbol that represents a number (unknown quantity). 8 + n = 12

20. A variable can use any letter of the alphabet. n + 5 x – 7 w - 25 Lesson 1 - Attachment A

21. b. Constant Constant-a quantity that does not change. The number 8 + n = 12

22. Algebraic expression – a group of numbers, symbols, and variables that express an operation or a series of operations. m + 8 r – 3 - 6r Lesson 1 - Attachment A c. Algebraic expression

23. Review Vocabulary Numerical Expression-An expression that only contains numbers and operations 5-6÷3

24. Which expression are ALGEBRAIC expressions 5x-4 3x-5y 5+t-t R-10 7-4 (5-2)+3 5-2+4 a+b+c

25. Input and output machine X=5 10 X+5

26. 2. Evaluating Algebraic expressions-TABLE a. Input given values into where x is in the expression! x x+2

27. b. Complete This Table

28. c. Complete This Table Lesson 1 - Attachment A

29. d. Complete This Table Lesson 1 - Attachment A

30. 3. Evaluate algebraic expressions-expression 4h-6 h=3 Substitute given value in where variable is Remember-once you substitute number in, the variable isn’t there anymore!

31. You Try!!! Evaluate when c=9 C – 3 c + 6.7 9c+10 Helpful Hints Multiplication can be written like: X • 3 3x X(3) Division can be written like: x÷3
