Aim: How to use the distributive property to simplify expressions?

HW: Do even numbers from both sides of today's worksheet.

Lesson Review: Use the Distributive Property 5(x + 3 ) + 2
Then combine like terms 5x + 15 + 2 = 5x + 17

2. Translation of english statements to algebraic expressions
3. Finding solutions sets for opens sentences for a given domain
4) Defining and recognizing the properties of real numbers.
5) Solve one and two step equations
6) Distribute terms in an expression
7) Combining terms of an an expression

Aim: How to solve equations by two or more steps?

HW: Do all questions on side 2 of worksheet.

Lesson Review: Again, decide on which inverse to use for the first step: additive or multiplicative.
Example 1: 3x + 4 = 10 -----use the additive inverse of +4
- 4 = - 4
then continue 3x = 6----------use the multiplicative inverse by dividing by 3
Solution x = 2

Aim: What is an open sentence?

HW: Worksheet - Do all the questions on side 2.

Lesson Review: An open sentence is a mathematical statement that contains two algebraic expressions and a symbol that compares them.

An equation is an open sentence that contains the symbol =. An inequality is an open sentence that contains one of the symbols <, >, less than or equal to, greater than or equal to.

Solutions:When you substitute a number for the variable in an open sentence like x + 2 = 5 or 2y>6, the resulting statement is either true or false. If the statement is True, the number is a solution of the equation or a solution of the inequality.

Aim: How do we evaluate algebraic expressions?

HW: Worksheet even numbers only

Lesson Review:
A variable is a letter used to represent one or more numbers. The numbers are the values of the variable.
An algebraic expression or variable expression,consists of numbers,variables and operations.
To evaluate an algebraic expression, substitute a number for the variable, perform the operation(s),and simplify the result, if necessary. The resulting number is the value of the expression.
