Announcements QUIZ FRIDAY!! Covering week 6 and 7 TURN IN HW!-lots of missing hw from last week-you can always get some credit, even if late EVERYTHING IS ONLINE-make sure you keep yourself up to date EXTRA CREDIT- Come after school today by 3 pm!

Open Sentence Equations 5x + 2 = 10 For x = 1 (7 + a)² = 4 For a = 2

Open Sentence Inequalities 10x – 12 < 25 For x = 6 2(3x – 2) > 4 For x = 5

Weekly Sheet DO NOW 1)3x – 6 = 18; for x = 7 2) 2(5x-1)+2x = 10; for x = 2 3) 7-8x+6=-23; for x = 3 Learning Goal/Objective SWBAT: -Simplify expressions to solve for a variable -Find solution set of open sentences Homework Finish both open sentence hw sheets begun in class

Homework Review 2) 4x²-3(5) = 12; for x=3 4) 17x-8(2x-4) = 32; for x = 3

Open Sentences and Simplifying 4a+5 = 17 {0,3,5,8,10}G = (15 * 6) (16-7)

Practice Problems #1-6(Top): Option 1: Test #s in the replacement sets in each equation to find solution Option 2: Solve for the variable to find the solution #1-8(Bottom): Simplify the numerical expressions to find the value of the variable. DO NOT USE A CALCULATOR

Weekly Sheet DO NOW Find the value of the variable: 1)T =7(8+6.5)-(-2) 2)X= ½ (8-2(6))+10 3)A = 9(5-3) (5*-2) Learning Goal/Objective SWBAT: -Use mathematical properties to simplify expressions Homework -Problems on powerpoint

Announcements REMEMBER: QUIZ FRIDAY!!!! -Learning goals -Classroom goal Videotaping-Bring home and have parent sign consent form Homework-Keep track of hw assignments and weekly sheet handed in on Friday

Homework Review-#5-8

Properties of Numbers Additive Identity Multiplicative Identity Multiplicative Property of Zero Commutative Property Associative Property A + 0 = A A * 1 = A A * 0 = 0 A + B = B + A; A * B = B * A (a + b) + c = a + (b + c) (ab) * c = a * (bc)

Homework Problems Test the value for the variable in the open equation or inequality: 1)7x(6-12)+5(2²) = -22 For x = 1 2)18-(-3)+x(5+6)² > 7 For x = 2 3)1*5(40-38)+9x-6x < 10 For x = 5 Find the value of the variable on your own! Guess and check or solve for the variable 1. b-6 = x = /n – 2 = x – 6 = a/ = 17
