Algebra

100

2x = 10

What is x?

x = 5

200

5x + 7 = 6x + 4

x = ?

x = 3

300

12 - 5x + y = 0

y = 2

What is x?

If y = 2:

12 - 5x + 2 = 0

Therefore 5x = 14

x = 14/5

400

Expand:

(x + 2)(3x - 6)

x * 3x + 2 * 3x - 6 * x - 2 * 6 equals:

3x squared + 6x - 6x - 12

500

10x - 10 = -y - 2

9x + y = 6

x = ?

y = ?

10x + y = 8

10x - 9x + y - y = x

8 - 6 = 2

Therefore x = 2

If x = 2:

18 + y = 6

Therefore:

y = -12

There are 10 people in a class with blue eyes, and 8 people with blond hair. 2 people have both blond hair and blue eyes. There are 28 people in the class.

P(Blue U Blond) = ?

14 / 28

Linear equations

100

y = x + 4

Draw a graph representing this information.

I will check it. 

200

y = 3x + 4

Draw this linear equation.

I will check it. 

300

y = -3x + 4

y = 2x  - 2

Find the intersection between these two lines without drawing a graph.

-3x + 4 = 2x - 2

5x = 2

x = 2/5

4/5 - 2 = -1 4/5

A hectare is ____ square metres.

10000

300

What is 3.5 metres cubed in Litres?

35 000 L

400

A square's dimensions are 6cm.

What is the area?

36cm squared

500

What is the volume of a rectangular prism with the dimensions of 10cm, 3cm, and 4cm.

The ratio between Sophia's toys and Edward Cheung's toys is 7:3.

If they have 50 toys in total, how many toys do they each have?

Sophia = 35

Edward Cheung = 15

200

Bailey's history mark compared to Edward's history mark is 25:6

If their total mark is equal to 155, what is Edward and Bailey's mark?

155 / 31 = 5

6 * 5 = 30

Therefore, Edward's mark is 30.

5 * 25 = 125

Therefore Bailey's mark is 125

300

A barbecue retail price is $250. It goes on sale for 25% and then goes on sale again for 10%. 

How much is the Barbecue's new price?

250 * 75% = 187.5

187.5 * 90% = $168.75
