the 4th growing post

Question#1: We've learned how to write algebraic equations in the form of mx + b = y. Convert these two sentances into algebraic equations using the above formula.

Sentence 1: Scott is 2 years older than Donald who turns 12 on June 16th 2006. Write this sentence in the format of mx + b = y, then convert it into an expression which allows us to figure out the age of Scott.
D + S = Y
11 + 2 = 13
Sentence 2: Elizabeth has $200 in her savings account. She makes $40 every two weeks babysitting for her next door neighbours. If Elizabeth saves all of her money solve for how much money she will have in one year.
200 + 40n

Question 2 : Creation. You need to create two questions for your classmates that cover diffrent concepts (ex: T-Charts, patterns, equations, graphs etc.) that you have learned in this unit on algebra. You then need to show how to sole the questions. Your mark will be based upon the level of question's difficulty, and the effort put into your answer .

1. 10a - 15 = 5a + 10

First of all you have to get all the variables on one side.
10a - 5a = 15 + 10

And then you have to add & subtract.
5a = 25
And finally you have to get the variable by it's self.
5a = 25
25 divided 5 a = 5

My pictures don't end up showing ?!

Question 3 : Reflection. You need to look back at the chart that we filled out during the first day of the unit. This is the chart where you coloured a topic red, yellow or green. You now need to pick one concept that you coloured yellow or red and reflect in words what new skill/idea that you have learned on this topic.

I learned how to create an algebraic formula in words and how to solve an unknown ( kind of ) .


Question 4 : Preparing for the final exam. You need to think about the yeat that has past in mathematics and decide which topic is your weakest, and what you need to learn during class review in order to prepare yourself for the finial exam. It is not enough to say fractions, instead pick your weakest area of fractions, say the subtraction of fractions, and give an example of what you don't under stand.


My weakest topic in math is algebra and intergers ? . I don't really know how to make equations and how to solve some equations and i forgot what intergers are .

To Figure out the next two diagrams you need to know how many chocolate chips are being added on to the cookie. There are four more chocolate chips being added on.

You now need to pick one concept that you coloured yellow or red and reflect in words what new skill/idea that you have learned on this topic.

On my chart I have coloured CAN I CREATE A T-CHART FOR MY PATTERN? in red. During this unit in algebra I can now make a T-Chart for my pattern.

MR.REECE MY DIAGRAM WON'T UPLOAD!!!!!!

My weakest topic in math is algebra. In algebra I am still having trouble with making equations from problems. An example of what I am having trouble with is the one we have on this growing post. I DON'T GET IT!!!!

Question 1: Formulas. We've learned how to write algebraic equations in the form of mx + b = y. Convert these two sentences into algebraic equations using the above formulas.

Sentence 1: Scott is 2 years older that Donald who turns 12 on June 21st 2006. Write this sentence in the format of mx + b = y, then convert it into an expression which allows us to figure out the age of Scott.

Don't get it.

Sentence 2:Elizabeth has $200 in her savings account. She makes $40 every two weeks babysitting for her next door neighbors. If Elizabeth saves all of her money solve for how much money will she have in one year.

200 + 40 (12)
40 x 12 = 480
480 + 200 = 680

If Elizabeth saved her money for a whole year she would have $680 dollars in her savings account.

Question 2:Creation. You need to create two questions for your classmates that cover different concepts (ex: T-Charts, patterns, equations, graphs etc.) that you have learned in this unit in Algebra. You then need to show how to solve the questions. Your mark will be based on the level of difficulty, and the effort put into your answer.

Are the tiles dcreasing each time or increasing? Would it be possible to make this into a graph? How would it look like?

The tiles are increasing each time by 5 tiles. Yes it would be possible to make this pattern into a graph.





This is how it would look like if I were to put it into a graph.









Lina has 40 marbles in a box. Every month she adds 15 more marbles to her collection. If she was going to keep collecting marbles for 2 years how many marbles will she have?

40 + 15(24)
15x24=360
360+40=400

In 2 years Lina will have 400 marbles in her collection.

Question 3: Reflection. You need to look back at the chart that we filled out during the first day of the unit. This is the chart where you coloured a topic red, yellow, or green. You need to pick one concept that you coloured yellow or red and reflect in words what new skill/idea that you have learned on this topic.

During our unit on algebra I learned how to use words to make an algebraic formula. For exmaple 4n = 14 four multiplied by a number is equal to 14.

Question 4:Preparing for the final exam.You need to think about the year that has past in mathematics and decide which topic is your weakest, and you need to learn during class review in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick your weakest area
area of fractions, say the subtraction of fractions, and give an example of what you don't understand.

I don't understand the long questions in algebra like: 5n+5n-2n=16n=2 There just seems to be so many things all there at the same time that I don't know which 1 to tackle first.

Note:Sorry if some of the sentences don't make any sense its really late at night and I'm tired. Plus I still need to study for a french test.

*Mackenzie's Third Growing Post*

Question # 1: What is the difference between an algebraic expression and an equation (hint: One contains this and the other doesn't)? Give an example of both an expression and an equation.

In an expression we get to chose the value of the variable Example: 10+20n=
In an equation the value of the variable is given Example: 3+4n=19

Question #2: What is a variable and why do we use one in algebra?

A variable is a letter that represents an unknown number. We use the variable to replace an unknow number.

Question #3: solve for N

A triangle = 5 because two squares = 4 so the whole left hand side of the scale has to equal 9 so the triangle = 5
The right hand side of the scale equals 22 and it is even so one n has to equal 11 because 22 divided by 2 equals 11 and there is 2 ns on the scale.

Question #4: Solve the following questions. Show all of the steps that are needed.

a) 3n + 4n + 7 = 2n + 12
3n + 4n - 2n = - 7 + 12
5n = 5
/5 /5
n = 1

b)8n - (4 + 9) = 11
8n - 13 = 11
8n = 11 + 13
8n = 24
/8 /8
n = 3

c) (8 - 3)n + 7n + 8 =4n +40
5n + 7n + 8 = 4n + 40
5n + 7n - 4n = -8 + 40
8n = 32
/8 /8
n = 4

Question #5: For this question you need to create a T-cahrt and a graph to plot your data from this question on too.

You are having a race against your friend, except you are on foot and he is on his bike. You both know that if you are both on a bike you will be faster so your friend gives you a head start of 3 minutes. If you can run 400m per minute, and your friend can bike 700m per minute, who willbe the first to make it to the finish line 2000m away

Question #1What is the difference between an algebraic expression and an equation (hint: one contains this and the other doesn't)? Give an example of both an expression and an equation.

an algebraic expression uses a letter for the unkown but an equation just has numbers
Expression: 5(n) + 40= 65 equation: 45+69=114
n= 5

Question #2What is a variable and why do we use one in algebra?

A quantity is capable of assuming any of a set of values & can be used in a expression or an equation.

Question #3 Solve for N
1 square - 2.1 circle - 1.1 triangle - 5.2n = 6 squares and 2 triangles (=22)
the represents eleven!

Question #4 Solve the following equations. Show all the steps that are needed.

a) 3n + 4n + 7 = 2n + 12
b) 8n - (4+9) =118n - 5 = 118/8 11/8n = 1.375
c) (8-3) n + 7 n + 8 = 4n + 40.


Number 5 will be here soon. it'll be here wen i learn how to get a picture from paint to this spot!

Growing Post#2

1a) Create a t-chart showing how many baseballcards Jack has at the end of the next 4 months.
















1b) Create an algebraic formula based upon the problem above
180+25*n (month)

1c) If Jack just turned 8 years old this month and Jack continues to buy the same amount of baseball cards each month, how many baseball cards will Jack have when he turns 12?
Jack will have 1380 baseball cards.

2a) If Jackie thinks that there will be four people at the party (counting herself) how many pizza's should she order?
She should order two pizza's.

2b) If two more people show up at the party how many more pizza's does she need to order?
SHe would need to order one more pizza.

3a) Calculate how much money Kathy will have in one year.
20+15*12=200

3b)Suppose Kathy counted wrong and she really has $25 in her account instead of $20.
Change the algebraic to reflect this miscalculation.
25+15*n or 25+15n

4a)3n+4n+7=2n+12


4b)8n-(4+9)=11

Growing post #3

1) What is the difference between an algebraic expression and an equation? Give an example of both an expression and an equation.
The difference is that equation is that the variable is only one number and in an expression it can be any number.
Equation:12t=24
Expression:14+s

2)What is a variable and why do we use one in algebra?
A variable is a letter that represents a number. We use them in algebra because they allow instructions to be specified in a general way.

3)Solve for N
a)4+n=9
-4 -4
n=5
