Unit 1 One Variable Equations & Inequalities

Unit 1 Vocabulary Flyswatter Activity Vocabulary definitions are available on Mrs Wolf Website

Vocabulary Algebraic Expressions Terms (numbers, variables, variables with numbers) linked together with an addition or subtraction sign. Coefficient Number in front of a variable Constant A term that has no variable and does not change Distributive Property Taking a term on the outside of a parenthesis and multiplying it to the inside. Ex a(b + c) = ab + ac

Equivalent Expressions Expressions that have the same value or simplest form Integers Positive and negative whole numbers and 0. Like terms Terms that have identical variable parts Order of Operations P.E.M.D.A.S. Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

Simplify To write an expression in simplest form (combine all like terms Substitute To replace Term Parts of an expression separated by addition and subtraction signs Variable A letter used to represent one or more number

What are some key words that represent the following operations? AdditionSubtraction MultiplicationDivision

Tips to Remember When multiplying a number and a variable, the number is written first Ex) 5x (NOT x5) Be careful of order with subtraction & division!! Ex) “5 – t” is very different from “t – 5”

Write the following expressions in algebraic form: 1) 9 more than c2) b minus 4 3) the quotient of z and 9 4) the total of n and 40

5) the sum of 8 and m 6) x divided by the quantity y plus 5 7) the difference of h and 7 8) 23 less than p

9) the product of g and 2 10) 77 plus twice v 11) two times r increased by 12 12) 3 times j decreased by 12

Examples: Identify the Like Terms 1) 2) 3)

Examples: Combine the like terms 1) 2) 3)

Distributive Property 1) 2) 3)

Evaluating Expressions 1. If a = 12, b = 5, and c = 4, evaluate: 3c + bc – 2a 2. If x=4, y=-2, and w=1/2, evaluate: 3. If p=-3, q=2, and u=8, evaluate:
