For question 18, it was 23

I got it wrong but I realised straight after

You had to do:
69 + x + 180- 4x= 180
Which gives you rearranged
-3x= -69
so x= 23


how about the one they aske for the gradient. did you get 2 over 3

what was the answer to that polygon question? It was so hard!


There was a question almost exactly the same in one of the mocks I did..it's to do with the interior angles of the pentagon

Yep y= 2/3x +5
As it had to pass through (6,9)
Took me ages to work out though haha!

I'm confident . The people in my school are actual genius' and they take maths a year early :smile:

It's definitely not 37 though cos I remember doing it in class.
You have 100 to start with. It increases by 20 so now it's 1.2 then you times it by 1.17 as it increases by that.

1.404 ... It's increased by 40.4


YES that's what I did, took a bit of thinking though :smile:)

I am almost certain that's wrong, it's 1/10.
P(2,2 + 3,1 +1,3) = 1/10
