Important definitions
Co-efficient- Is any certain number that you can multiply a variable with, the co-efficient can be negative or positive.(example) 2x + 1 = 9  

Constant- Are any numbers that are a part of the equation. They always stay the same.
                  (example) 2x +1 = 9

Variable- Is any letter that can represent any unknown number.
                ( example) 2x + 1 = 9  


Steps to solve multiplication equation
1. Isolate the Variable
2. Cancel the Constant
3. Balance
4. Simplify
5. Cancel Coefficient
6. Balane
7. Simplify
8. Verify


2 step multiply

 Question
4x+3+3=1

Step 1. 4x+3=18+1 is 4x+1=19
Step 2. 4x+3=19, so you have to cancel the constant, 4x+3-3 = 19-3 = 16
Step 3. 4x=16, Now cancel the coefficient
Step 4. 4x/4 = 16/4
Step 5. x=4

How to solve division equation
1. Isolate the variable
2. Cancel the constant
3. Multiply
4. Verify

2 step divide

Step 1. x/3+6=9
Step 2. x/3+6-6=9-6 = x/3=3
Step 3. (3)x/3=3(3)
x=6


How to solve a distributive equation
1. Multiply whatever is inside the brackets by whats outside the brackets.


Distributive equation
Step 1. 4(x+6)=28
Step 2. 4x+6(4)=28
Step 3. 4x+24=28
Step 4. 4x+24-24=28-24
Step 5. 4x=4
x=1

Tommy's Integers Post

3 questions.

I will answer 3 questions with 1 different way for each.

Way 1. A number line.

1. (-6) + (+8)

Way 2. You can use words/money to help you.

2. (-8) + (+7)

Way 3. You can use circles. There are 2 different circles, a shaded one, and a non-shaded one. The shaded ones are positive, and the non-shaded ones are negative.

3. (-7) + (+9)

Hope these tips taught you how to add positive and negative integers.

Tommy's Proportion Post

Part 1
Ratio-  A ratio shows the relative sizes of two or more values
Example


Rate - A comparison of 2 quantities that have different units of measure
Example

Proportion -  An equation which states that two ratios are equal

Example

Part 2

1) 5 hours to travel 360 kilo meters is about ___ km/h

72 km/h

2) Emma saves 28 cents of every dollar that she earns. Emma earned 75$ last week.  How much money did Emma save last week?

She saved 21 dollars last week

Part 3

What are the three ways you can prove that equivalent ratio statements are true?

3/4 = 12/16  or 4/9 = 16/32

1. Using time table

2. Dividing it

3. Multiplying it

Part 4

Part 5
1. Does this seem fair?
 No it isn't fair.
2.With what you know about proportion look and read what is in the image above.  Does it seem just and fair? 
100 dollars for 15 years? Too much. It should be about few thousand or tens of thousands to be 15 years. So no, it does not seem just or fair.

3.Why have you made this choice? 

Because 15 years is way too much for 100 dollars, and that guy was homeless now I feel bad for him.

4.What would you have done if you were the judge?

I would let him in jail for a week or so, because he only stole 100 dollars, and he gave it back and admit he stole it.
