»» 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
