2. Note taking: All powerpoints will be color coded as follows:
RED means COPY (write it down!)
BLACK means READ
YELLOW means READ and REFLECT
BLUE means DO
GREEN means NEW ASSIGNMENT (might need to be written down in your planners)

3. Homework review!

4. less than – reverses the order
5 less than b : b – 5

5. 10 plus a number, times 8
How should this be written? How should the following be written: 10 plus a number times 8 Is there a difference?

6. Expressions Vs Equations
We know: Algebraic Expression is an phrase that contains one or more variables Equation- any math sentence using the verb “=” Ex: x + 5 = 3

7. Equation or expression? Together!
X = 5y

8. Equation or expression?
5 – 10 = y
3x -2 4x

9. Changing verbal sentences to equations – together!
1.The quotient of b and 9 is Twice b is 3 less than 2.

10. Practice
The sum of a and 4 is 12.
Three-fourths of a number is 5.

11. Inequalities
Inequalities- a sentence with one of the verbs listed below. ≠ is not equal to ≤ is less than or equal to ≥ greater than or equal to ≈ is approximately equal to

12. Together!
2 is less than 3.
The sum of t and u, divided by 6 is not equal to 3.

13. Practice The product of 5r and s is greater than or equal to 10.
The sum of t and u divided by 6 is 7.
Twice the difference of 2 and x is 11.

14. Less than VS is less than VS Less
b less than a
a - b
Ex: 4 less than 5
5 - 4
b is less than a
b >a
Example: 4 is less than 5.
4 < 5
B less a
B – a
Example: 4 less 5
4 - 5

15. Together!
x >3
2(n + 3) ≠ 5
100 – 2x ≤ 5

16. Write the following equations/inequalities into English sentences:
X ≥ 5
X + 5 ≈ 6
y ≠ 5
x – y = 4

17. On a separate sheet of paper with your first and last name on it, answer the following:
10 plus a number, divided by 2
Is there a difference between:
and
10 plus a number divided by 2? Explain.
