here is an algebraic equation: 2x+5=13
the first step your going to do is to isolate the variable canceling he constant which would look like this   

2x+5-5=13-5

because we've added -5
to the left we need o add -5 to the right balance

Once you have balanced both sides you will divide both sides by 2 which
look like this

2x=8
2     2

Then you cancel the twos your left of with x then you divide
8 and 2 then you get x=4

now you verify by using the original equation
2x+5=13

Then substitute the value of x which is 4
SO
now
2(4)+5=13
8+5=13
13=13
now, I know that my answer is right because
they are balance

pay it forward

what i did for pay it forward was make my bed so my mom dosent need to do it but i do it most of the time so decided to do when she was about to do it.

proportion post

part 1

ratio ; is a relationship between two numbers of the same kind.

rate: a comparison of two quantities that measure in different units

proportion: an equation that says that two ratios or two rates are equal


part 2   

1. 5 hours to travel 360 kilometers is about 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 $2.67

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

4/9 is not equivalent 

3/4 is equivalent     

part 4: http://youtu.be/u6hxkCwlK5k 

part 5

1. no this is not fair

2. 15 x 12months=180months divide $100= .55 a months
      3 000 000 000.00 divide 40= 7,500,000months

this does not seem fair 

if i was the judge i would of given the homeless guy like a night in jail and the other guy that stole 3  billion would of given him 15 years in jail.
