Scribe Post for Feburary 2, 2009
Hey guys. Happy ground hog day!
Anyway, today in class we took a test. It mostly had word problems.
We also did page 50, questions 1 - 6. This is homework by the way. He showed us how to do the first two questions in class. Here they are:
Anyway, today in class we took a test. It mostly had word problems.
We also did page 50, questions 1 - 6. This is homework by the way. He showed us how to do the first two questions in class. Here they are:
x + 3 (x + 4) = 20
Now do the distributive property for the following things in red:
x + 3 (x + 4) = 20
You have to multiply the 3 with the x and the 4, so now it looks like this:
x + 3x + 12 = 20
Combine the x and the 3x (like terms):
4x + 12 = 20
Get rid of the constant by adding negative 12 to both sides:
4x + 12 = 20
- 12 - 12
Now the question is 4x = 8. Isolate the variable by dividing the 4:
4x / 4 = 8 / 4
You are now left with the answer of:
x = 2
Remember to verify!
The second question he gave us was:
6 ( y - 1) + 8 = 32
Do the distributive property:
6y - 6 + 8 = 32
Now combine the like terms, which in this case are the constants:
6y + 2 = 32
Get rid of the constant by adding negative 2 to both sides:
6y + 2 = 32
- 2 - 2
Now isolate the variable by dividing both sides by 6:
6y / 6 = 30 / 6
Your answer is:
y = 5
REMEMBER TO VERIFY!
Anyway, I hope that was even just a little bit helpful. Thank you SO much for reading my post! Remember that the homework is page 50, questions 1 - 6. Thank you! Please comment.
By the way, I choose Elmane to be the next scribe!

I love how you used the different colors. I am a math person and teach college kids about accounting. I am trying to learn about blogging so I can make it more interesting and understandible. Thanks for the examples.
