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:


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!

Good job Kristin, you explained it very well, and you used different clours like, one colour for the equations and one colour for the answers, I also agree with Zerlina it's very understandable.

Kristen

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.
