Alyssa's Growing Post #4

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.

You did a great job with creating questions. For the second sentence the number of weeks is 26.

Your mark is 20/25
