Todays work and a test tomorrow.

Tomorrow you have a test on Algebra. You need to know all about the "Sammy the Seal" booklet.
Two questions you will have are 7x -2 = 3x +10 and 7x + 4 - 5x = 30. In class we studied experssions to tables to graphs. Examples of the questions are

Question 1



Question 2

Question 3


Scribes for today can use these three questions to add pictures to your scribe posts (graphs and tables).

Answer the questions in the comment box on this post. There will be a question like this on your test tomorrow. Blogging gets you extra marks!!

For the cart one I found it easy.

32inches the first cart. Everyone add 11inches

1 32
2 43
3 54
4 65
5 76
6 87


For 20 carts you can just go

32+19x11

an expression

32+11x=y
