The best way to approach this is to catch up the lessons you missed. Go to youtube or http://khanacademy.org and search for the maths topics you missed.

You will find great, easy to follow video guides on there to explain how to tackle these problems.

OMG.
you cant do one single problem yourself?
stop sniveling…
use a search engine to find some math website that will TEACH you how to do these yourself, instead of getting the answers without learning to even do them.
us giving you the answer isn’t going to help you at all!

lol.

I MANAGED QUITE A BIT ON MY OWN :’D

I didn’t manage these :

PROBLEM 3: A line has a gradient of 3 and its y-intercept is 4. Write the equation of the line.

PROBLEM 5: A triangle has an area of 48cm². Its base is 12cm. Find its height.

PROBLEM 6: Simplify the ratio 2½ : 3.

Omg, I feel so smart(er).
JUST those 3 ?(:

hmmm.
well, you need the formula to do problem 5 and instead of doing what the formula says, like add or multiply, you need to find the height so you’ll need to subtract or divide instead, depending on whatever it says to do to find the area.

1. 4(a^2-2b+3)
2. -36
3. y=3x+4 (see the thing here is that you gotta know the formula, y=mx+b, m is the gradient and b is the y-intercept, then just substitute the values ;])
4. 157.5 (rough estimate)
5. 8cm
6. 5:5 (not sure)
7.0.1024 (its an estimate not that accurate)
8. 5x(y-2x)
9. 231.6
10. 21600 (also an estimate)
11. -4

Glad to help :)
