### »» SRIBE FOR MAY 19`06

» K so first we did "Words and Symbols" from the smartboard.

1. A number increases by 5

**= n + 5**

2. A number decreases by 7 =

**n - 4**

3. A number divided by 3 =

**n ÷ 3**

4. The sum of 7 and a number =

**7 + n**

5. A number multiplied by 4 =

**n x 4**

6. 8 subtracted from a number =

**n - 8**

7. A number subtracted by 9 =

**9 - n**

8. Half of a number =

**n/2**

9. 25 divided by a number =

**25 ÷ n**

10. 10 decreased by n =

**10 - n**

» Then, we looked at the homework from May 18 about the parking lot

» After that.. Mr.Reece explained how to do some of the growing post questions on blogger.

» We took down important notes about Algebraic Expression and Equation. If you were'nt there on that day we did this, here's your chance to copy it (:

**Expression :**In an expression we get to choose the value of the variable

Example - 3 + 4n (START + CHANGE (VARIABLE) =

**Equation :**In an equation the value of the variable is given.

Example - 3 + 4n = 19

* it's trying to find what "n" stands for.

*Steps for Solving Algerbraic Equations*

**1. Solve all the brackets**

(8 - 2) n + 5n = 18 + 2n --> 6n + 5n = 18 + 2n

**2. Combine like terms that are on the same side of the "=" symbol.**

6n + 5n = 18 + 2n --> 11n = 18 + 2n

**3. Combine all variables onto one side of the "=" sign.**

Example: 11n = 18 + 2n --> 11n - 2n = 18 + 2n - 2n --> 9n = 18

**4. Solve for the given variable**

Example: 9n = 18 --> 9n/9 = 18/9 --> n = 2

*DONT FORGET..*Growing Post DUE on Tuesday

The Sribe for Tuesday is Boeun xP xP
