Hello everyone.
Hope the exam went well for you.
I'm 100000% confident the answers I got are correct, hence I'm making this Unofficial Mark scheme.
Q.1) Factorise and solve the equation for x and the answer is 8.
Q.2)There was a Nth term sequence going up by 2n each time.
On the diagram you were give n,2n,_,_
You had to work out the total value of the first 4 terms and The answer was 135.
Q.3)
a)Plotting for Train A
b)Plotting for Train B.
c)80mph was the speed of train B.
Q.4)
Car B was cheaper.
Q.5)
7 blue discs.
Question 6)
Factorise to get: 2x(3x+7)
Q.7)
You had to list all the values that satisfied The Inequality and they were:
3,2,1,0,1
Q.7)
b)Draw a line to represent the Inequality of 2< x >=10
You should have put a solid dot at 10 and clear one at 2.
Q.8)
John and Nick share money in ratio 5:2. They have a difference of £150
Work out how much in total they get.
Answer was £350
Q.9)
a)Find Reciprocal of 0.2 and Answer is 5.
b)What is 8.5^0 and Answer is 1
c)Factorise 27^1/3 x 7^2
Leave your answer in Fraction form.
Answer is 3/49
10) You had a graph and you had to state all the Inequalities for the shaded region.
They were:
x+y < 7 and x >= 2 y > 1
11) The question had something like this:
x20 : x + 280 is meant to = 1/4 or something like that.
Basically you had to find a value for x that satisfied that and made it = 1/4.
Answer was 120.
12)a)Forgot
12)b)Forgot
Please remind me of these questions... I know there were a few to do on surds.
15)Simplify an expression and I'm not sure whether you had to leave it at 2x1/2x+5 or 1/5 (CORRECT ME)
16)You had to find its identity something like that and
a=6
b=9
17)You had some Fractions and you had to turn it into a Quadratic then solve it, The answers were x=7 or x=4
I've forgotten some of the questions. If you tell me them I shall remember the answers. Have any disagreements or thoughts? Leave a comment below.

I shall clean this up when I get home....
The last question was solving a quadratic equation from the algebraic fractions, which I can't remember. I messed this up and made the wrong quadratic.
There was a question where we had to simplify an algebraic fraction (I think it had 2x on both the denominator and numerator).
If I remember anything else, I'll tell you.

That was a solid paper... I've only got 25 so far (My A grade is out of the window for sure).

There was a number machine question which involved you using Simultaneous equations to solve a and b.
I have the answer but can't remember the question, If anyone can tell me I can add it it.

a + b = 64
Something to do with those. I ****ed up the simultaneous equation!

I didn't sit the paper (Just passing ) but if it wanted you to solve the above for a and b....
a + (3a  5) = 64
4a  5 = 64
4a = 69
a = 17.25
b = 46.75
I know for a fact that the second part is not as Vardy stated.

input > x3 > 5 > output
when input is a, output is b
a+b= 64

Can't believe I've forgotten how I worked out my answers, but I know I didn't get the same answers. Perhaps I went wrong?
3a5=b
3(a+b)5=64
3(a+3a5)5=64
3a+9a155=64
12a20=64
12a=84
a=7
input 'a' into 3a5=b :
7x35=b
215=b
b=16Post rating:2

i think i made a mistake in my previous comment, i meant that if the input is a+b, the output is 64. i might be wrong but this is how i did it in the exam:
3a5=b
3(a+b)5=64
3(a+3a5)5=64
3a+9a155=64
12a20=64
12a=84
a=7
input 'a' into 3a5=b :
7x35=b
215=b
b=16
I did the same

You said a is 7 and b is 16 but 16 + 7 does not = 64....

"15)Simplify an expression and I'm not sure whether you had to leave it at 2x1/2x+5 or 1/5"
2x1/2x+5 does not equal 1/5 because you can't take 2x out of either top or bottom, it is not a factor.
2x1/2x+5 is correctPost rating:1

That's wrong (I think) though because the original statement said a + b = 64
You said a is 7 and b is 16 but 16 + 7 does not = 64....
i thought the exam said that when the input is a+b the output is 64
16+7=23
23x3=69
695=64
but maybe i misread it lolLast edited by slimehigh; 09062016 at 12:56.

I am confident i got this question right but cant remember with accuracy my answer or the question.
I do remember something along the lines of 3(a+b)5 but only vaguely.
