Variables and Expressions (evaluate) 3/14/2016 TSWBAT: evaluate an Algebraic expression. Students simplify expressions before solving linear equations and inequalities in one variable, such as 3(2x - 5) + 4(x - 2) = 12.

Notes Definitions - Evaluate = to find the value of an expression - Replacement Set = a set of numbers that can be substituted for a variable - Variable = a letter or symbol used to represent a value Ex. - Expression = contains variables, numbers, and/or operations

Notes Evaluate each expression for the replacement set Ex.
