Note: I'm sorry for the super late post Mr. Backe and class, my computer got a virus and was sent to be fixed last Monday and I just got it back today so I am really, really sorry.

So today, Mr. Backe gave us questions to identify the number of terms, name and degree of an expression like this:




















I think it's pretty easy but he let's us practice because he wants to make sure that we all get it because this stuff is important. He also mentioned polynomials being part of what we need for Grade 10 especially for people taking Pre-Cal. He' going to be talking more and more about it and he's going to teach us "fun" Grade 10 stuff. I never found Math "fun" but maybe it will be. He also made us do matching words (match words and definition). It was really easy because all of the words were in my notes and I know almost all of them except for like terms, terms that only differ only by their numerical coefficients. After, he assigned us assignments, questions from the textbooks, and then he stopped talking and let us do our own work, quietly. I wasn't quiet and he knows that...I finished 5 questions though (:
It's hard for me to do work in class, I need a silent environment and plus and get distracted easily.

Hello 9-05 welcome back from a long break. Well now it's time for more school and yes we had math today.

Today we talked about question 21 in section 8.3 (textbook). The question went a little something like this......

A square picture is made out of wood that is 1.6 cm wide. The perimeter of the outside of the frame is 75.2 cm. What is the side length of the largest square picture that the frame will display?




















Well really what the question is asking you is what the side length of the middle square is.

Now to solve this you have to look at the width first.






















Since you know that the width is 1.6 cm and it will also be 1.6 cm on the other side between the small square and the perimeter, you can multiply 1.6 cm by two.





















Once you get your answer which is 3.2, you have to divide 75.2 (perimeter) by 4 so you could get the side length each side of the outside of the frame. You want to do this because if you multiply 3.2 (width times 2) by the side length of the outside which 18.2 you will get the side length of the inside square.

Did you get an answer of 15.6? Well if you did then you have got the right answer.

After solving that question we went onto question 27 also in section 8.3 (textbook) which was even difficult for Mr. Backe to solve. Well here is the question...

Tahir is training for an upcoming cross-country meet. He runs 13 km, three times a week. His goal is to increase his average speed by 1.5 km/h, so that he can complete each run in 1 1/4. How long does he take to complete each run now, to the nearest tenth of a minute. Solve this problem in two different ways.

Well I am not really sure how to solve this but this is what Mr.Backe did.














Thats all for today and sorry it is so late. Bye.

Hey there :) , Sorry this is late.. I kept forgetting my journal in my locker -_-" I finally remembered to take it home.. cause Backe wrote it on my hand. Or should I say my finger -_-" Beautiful..



Anyways .. I will talk about something in Chapter 6. This is coming straight from my journal. When you read it dont make fun of me -_-" I talk as if my journal is a diary.. LOL. So here it goes :)


Today in class, Backe asked if we have any questions or anything. No one did suprisingly.. The class was so quiete.. It was amazing. Well after that, he started talking about some patterns and things. Well there went the class.. We were talking about some pictures or something. Wait i'll show you. Just wait let me draw it :)








See this is what we are learning. We have to find out what the how many squares are in the fourth and fifth figure and the "linear equation" or something. Well yeah, I'm so lost.. Like you don't even understand.. But wait, I'll ask questions BE RIGHT BACK.



Okay I'm back.. Hey there! Well my questions helped me, I get it know ! yay me :) I'm going to go do it on my loose leaf! Bye Journal :) I wrote a lot in you today ! yay me :)

Hello 9-05. Today i didn't really take good notes today but Ill type what i have down. So today in class we started giving back our foldables which alot of us including me didn't hand in yet. I then Mr. Backe yelled at us and blah blah blah... Okay well after that we talked about our homework on 8.1. Then most of the class he th0ught us things that i think were new things unless I am mistaken. Anyways I didnt get what Joseph said about the recirpical but i got this stuff. I hope you understand... Enjoy!!!

One of the questions he gave us too solve is....

ax+b=c .

I cant really show how to work it out but what you do is divide both by "A" and minus "C" by "B".

it should look like this...


ax=c-b
__ __ x=c-b
a . a . __
. a

The dots are here^^ because I can't move it over without anything there.
Sorry if its really bad!
