Footnote: The answers (because I can't cram the answers into a single comment box.)
Also note that:
a) My dad did this and he used his own method.
b) I didn't have to teach him a method to solve the problems.
c) I am not making any of this up.
d) It is hard to make a blog post on an iPad, please bear with me.

Yep.
(Also in radical 720p HD).

Textbook 9.2: Patterns in a Table of Values (14, 16, 18) Scribepost.

The algebra post that contains the questions that may or may not turn your brain into mush.

14. b) Let f = Figures

Let s = Squares

 3f + 1.

14. c) 61 squares (20 x 3 + 1 = 61)

14. d) 30 squares

Figure 10: 10 x 3 + 1 = 31.

So: 61 - 31 = 30.

Let h = Height (m)

Let t = Temperature (C)

16. c) Since the h and t values are consistent, then yes, the ordered pairs are linear as the graph shows.

16. d) 1050 metres.

Let r = Rental Cost

Let p = People

18. c) r ÷ 5

Wow, that actually wasn't hard.

Also graph paper.

Aniane's Proportion Post

Part 1

Ratio - The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

Can be written as:

Rate - Compares two quantities measured in two different units.

Example: 1000000 km/ second

Proportion - A part, share, or number considered in comparative relation to a whole.

Part 2

1. 5 hours to travel 360 kilometres is about 6 km/h. 1. 300 mins/360 km = 60 mins/ 72 km

360 ÷ 60 = 6 

6 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? 2. 28 cents/ 100 cents = 268 cents/ 7500 cents. 

0.28 x 75 = 21

$21

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

Vertical Multiplication:

Horizontal Multiplication:

Cross Multiplication:

Part 4

Part 5:

1. This does NOT seem fair.

2. The ex CEO stole 3 billion dollars and is sent to prison for only 40 months, while the homeless man only stole $100 and sent to prison for 15 years, which is pretty darn long considering the circumstances.

3. This, for me, is unacceptable. A homeless man robbed a bank, only trying to get $100 to stay at the detox centre and got arrested and got sentenced to jail for 15 years. And the CEO only got 40 months for stealing $3 billion.

4. OK, I know stealing is wrong, but come on, the circumstances made the verdict unfair. If I were the judge I would make a more fair and just verdict to both the CEO and the homeless man.
