Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. I missed the key for question 1... Of all the marks to lose it just had to be that xD
2. (Original post by ThatCreepyGuy)
23. Was part a of 24.
The answer for 23 was 28.9cm
23 was 29.25

I = 5(14.5-8.65)
I = 29.25

I said 9 out of 20 but as a fractition
I don't understand why ppl don't simplify the fraction? You have a calculator? All you had to do was hit sd

Reps are not necessary but would be appreciated

It would be really useful if you could remember the question numbers
1. Order numbers correctly and include a key
b) 9/20=
0.45
2a. 5a*2b*3c =
30abc
b. Factorise fully 3y +6 =
3(y+2)
c. Expand x(x-3)=
x^2-3x
3.
x=9.25
4. Smallest packet was best value for money because it was cheapest per bag of crisps
5. 4 times as many red than green: There were 0.4 blue and 0.15 yellow.
0.4+0.15+4x+x=1
0.55+5x=1
5x=0.45
x=0.09
4x=0.36
Green- 0.09 Red- 0.36
6a. 20.3
b. 68.04kg

18. 10a^5b^4
b. y= 5p^2-x

21. 29.25
22. F.d- 1.6, 3.2, 2.4, 1.8, 0.3
23. -1/3x+4
24. 2x/(x+1)(x-1)
25. 80.4

I missed the key for question 1... Of all the marks to lose it just had to be that xD
I also forgot the key ((((((

i am also worried i put 11/20 instead of 9/20.

i might be overthinking it
7. Anyone remember the questions for 6a, 7 and 10???
8. Which question was the question asking on price of petrol and parking total cost? i got something like £8
9. I got the medium packet for the crisps one! I got the small one first but then o crossed my working out and changed the numbers around on the calculator and got the medium one to be the cheapest! I'm so confused - that's 4 marks DOWN THE GUTTER. I HAVE FAILED THIS PAPER AND THE NON CALC PAPER TOO! WOOO!!!!
10. (Original post by Disfuligee)
Actually 2x/(x+1)(x-1) is more simplified
Literally every year the exam board allows both lol
11. (Original post by Oasis61)
How many marks would this get
3-x/(2x+4)(x-3)

Posted from TSR Mobile
Sorry but I think that is none because that does not multiply out to 3x^2-5x-12 or whatever the original was

Please would you be able to put how many marks each answer is worth? Thank You
Also I got 126 degrees for question 9
13. (Original post by xsophie_daviesx)
For the simplifying quadratic fraction I got -3x-4
Anyone else???
sameee
14. Can you write a probablity as a percentage for the second I did 9/20 X 100= 45% would that be fine?
15. (Original post by SweetStarlight14)
It was the perimeter that was 45cm, so 4x+8 = 45, meaning x = 9.25.
thank you so much, i hope that's right cos i got that too

True

How could you get 8? With £3.50 a day for parking, for 5 days, even the car park charge is higher than £8, let alone with the fuel as well
