In this blog it will tell you definitions and show you how to 2 step multiply, 2 step divide and distribute

Definitions
Coefficient - The number that is placed before and multiplied by the variable.
e.g. 2x+4=10

Constant - A quantity that does not change its value.
e.g. 2x+4=10

Variable - A letter or symbol that is used to represent a number.
e.g. 2x+4=10 


2 step multiply
3x+4=10

The first thing you do is isolate the variable. To isolate the variable you need to make a zero pair for the constant.
3x+4-4=10-4

After you isolate the variable you balance it, by dividing both sides by the coefficient and after that you simplify it. 
3x=6
3    3
x=2

Once you've find the solution, you verify by first rewriting the question.
3x+4=10

Then you change the variable to the solution and multiply. In this case the solution is 2 and you multiply the coefficient (3) to 2.
3(2)+4=10

After you multiply you add the coefficient to the constant..
6+4=10

And you got your answer.
10=10


2 step divide
x+5=8
2

First you isolate the variable like when you do multiplication by making a zero pair for your constant.
x+5-5=8-5
2


After you isolate the variable you balance it, by multiplying both sides by 2.
(2)x=3(2)
    2
x=6

Now you verify, by rewriting the question.
x+5=8
2 

Substitute or change the variable to the solution.
6+5=8
2

Now you divide the coefficient.
3+5=8

And that's how you to 2 step divide.
8=8


Distribute
2(g+4)=-8

To distribute you first multiply the coefficient to the constant and variable
2(g+4)=-8
   g+4
   g+4

and you get.
2g+8=-8

Now you find the solution, by doing the 2 step multiply. 
2g+8=-8
2g+8-8=-8-8
2g=-16
2       2
g=-8

Now you verify by doing the 2 step multiply.
2g+8=-8
2(-8)+8=-8
-16+8=-8
-8=-8

And that's how you distribute. I hope you learned about something in this blog.

Ch.9 Chapter Review 

7. Klaus works after school. The graph shows his rate of pay.

a)
b) Yes it represents a linear relation because the points lie on a straight line and its a recursive pattern.
c) Yes its possible because you work in not whole hours.

10.The table of values represents a linear relation.
a)
b) The difference in the consecutive A values is 1 and the difference in the consecutive B values is 4.
c) 4 times A plus 1 equals or 4a+1

12. Speedy print shop charges $2 for the the first colour copies and $1 for each additional colour copy.

a)
b) No because the points don't lie on a straight line and the cost($) is not a recursive pattern
c) c+1

d) 13

13. Craig travels at constant speed in kilometers per hour. The formula d= 15t represents the relationship.
a) d represents distance and t represents time
b) 15 represents how many kilometers Craig travels per hour.
c)
d)
e) Yes its possible because you could travel in not whole hours.
f)120 km

2. To model (-3) x (-5), Raini places 15 zero pairs on her desk.
a) Why did she use 15 zero pairs?
She used 15 zero pairs because she needed to remove 3 groups of -5.
b) What should she do next? 
She should remove 3 groups of -5.


8. Write each expression as a repeated addition.
a) (+7) x (+2) 2+2+2+2+2+2+2
b) (+4) x (-9) -9+-9+-9+-9


13. Copy and complete each multiplication statement.
a) (+4) x (+6) = (+24)                    b) (+7) x (-2) = (-14)

c) (-1) x (+5) = (-5)                        d) (-8) x (-2) = (+16)


15. An aircraft descends at 3 m/s for 12 s. Use the multiplication of two integers to represent the situation. How far does the aircraft descend?
(+12) x (-3) = (-36)
The aircraft descends 36 m

Lloyd's Proportion post

Lloyd's Proportion post

Part 1 Define

Ratio: A comparison of 2 quantities that have the same unit of measure 

Example:  

Footballs to all the balls is 3:5

Rate: Compares 2 quantities measured in different units

Example: Usain Bolt travels 100 mt in 9 seconds is 100mt/9sec




Proportion: Equation that tells 2 ratios are equal
Example:

Part 2 Answer using proportion statements 

1. 5 hours to travel 360 km is about       km/h

 2. Emma saves 28 cents of every dollar she earns. Emma earned 75 dollars last week. How much money did she save last week. She saved 21$ 

Part 3 what are three ways that you can prove equivalent ratio statements are true

Part 4 find a video about using proportion and embed it into your post

Part 5 What do you think about this image below.

1. Does this seem fair?
2.With what do you know about proportion look and read what is in the image above Does it seem just and fair?
3.Why you made this choice?
4.What would you have done if you were the judge?


1.No its not fair
2.No its not even fair
3.Because the homeless man only stole 100$ and he's sent to jail for 15 years and the other guy stole 3 billion $ and he's sent to jail for 40 months. That's not even close to fair.
4.If I was the judge I would send the homeless guy to jail for 3 months and I would send the other guy to jail for 15 months.
