1. HW: Maintenance Sheet 7. 10. Due Friday
HW: Maintenance Sheet 7.10 *Due Friday *Correction: Question 16 & 17 goes together
Bellringer *write down in your notebook
1. Josh is n years old. In 13 years he will be 24.
n + 13 = 24
= n
13 + n = 24
= n
none of the above  
2. Twelve is sixteen less than four times a number
12 = n
12 = n
12 = 4n - 16
= 4n
12 = 16n - 4

Perimeter of rectangle = _ _ _ _ _ _ _ _ _ _ _ _

7. Writing Algebraic Expressions
Which two expressions are equivalent?
Learning Target
I can solve linear equations with one variable and match scenarios to represent those equations

8. Which Equations Describe The Story?
A pencil costs $2 less than a notebook.
A pen costs 3 times as much as a pencil.
The pen costs $9
Which of the four equations opposite describe this story?
Let x represent the cost of notebook.
Learning Target
I can solve linear equations with one variable and match scenarios to represent those equations

9. Discussion
If x is the cost of a notebook, what expression will give the cost of a pencil?
[x – 2.]
If a pen costs 3 times as much as a pencil, what expression will give the cost of a pen?
[3(x - 2) or 3x – 6.]
What mistakes have been made with B and C?
[The expression x - 2 has been multiplied by 3 incorrectly in both cases.]
OK, so what is the cost of the notebook?
[$5.]
Can we check that this fits our equations?
