1. 2.) 6 times the difference between X and 9 3.) Half of R times 5
Warm-up October 12, 2017
1.) (6T – 7E) + (4T + 11E)
2.) 6 times the difference between X and 9
3.) Half of R times 5
4.) (6T – 7E) – (4T + 11E) C

2. One-Step equations Identify the variable
Figure out what operation is being done to the variable (+, -, X, or ÷ )
Perform the opposite operation on BOTH sides of the equation (Properties of Equality) – remember the operation has a number with it
T + 5 = operation is “ADDING 5”
T + 5 – 5 = 15 – 5 so T = 10

3. Two-step equations Identify the variable
Identify the constant side of the equation
You will be left with an addition or subtraction operation – do the opposite to move the number to the constant side
Re-write what’s left as a one-step equation
You will be left with a multiplication or division operation – do the opposite to move the number to the constant side

4. Go to the Guided Practice problems on page 274
Can you use a calculator for problems 1 and 2?
Can you use a calculator for problem 3?
Now what?

5. Class work Chapter 4, Lesson 3, pages 275 and 276
Problems 1 – 6 and 12
What is not completed in class is HW
Use your time wisely………….

6. Write an algebraic expression Ticket out the Door
35 more than 28 times R
The difference between 13 and the product of 26 and Y
One tenth of T plus 47
The quotient of 6 and a number Y, increased by one
Kevin is k years old. His brother Abe is 4 years younger than Kevin. Represent how old Abe will be in 20 years.

7. 28R or R
26 Y T/
6/Y
K or K

8. Simplifying algebraic expressions practice
1.) 6B + (-8B) + 5B + 3V – (-2V) 2.) - 6G + 5T + (-3G) – 2T – 4G 3.) 9H + 12H – (-13H) + (-6) + (-4J) 4.) 6M – (-3M) – (-5M) + 8U – 12U 5.) 8K + (-2W) – (-7K) W – 3W – (-7) TOTD

9. Use the distributive property and combine like terms
11.) -6 (-5M + (-6G))
12.) 5 (4H – (-4L))
13.) 3 (3D + 3E) + 7(5D – 6E)
14.) 14B + (-12B) + -5(7Y – 9K)
15.) 11A + 3E + (5E + (-2A)) + (5)(5F - 7R)
