Algebra I: Test tomorrow!
Here are the answers to the group test (ones not covered in class):
11) 1/2 or .5 or 50 cents

12) 50

13) 3 hours

14) the system is: y = 43x
y = 33x + 40

when you graph and solve it, you get x = 4


15) first dot: 3.5r + 5cn = 30.50

second dot: x + y = 7

third dot: 3 regulars, 4 new releases.

fourth dot: you have to plug (3,4) back into both equations and make sure it works.

Feel free to drop by before school or during your lunch period to ask me questions!




Algebra II: I don't remember what exactly the assignment is. If you were relying on getting it from the website, simply give me the password, "I can't believe it's not butter," quietly tomorrow and we'll talk.
