Median: Reorder the data in numerical order, then select the value that lies directly in the middle of the data line - if there is an odd number of data, the median value is the middle number and if there...

First off multiply m and x together. This is -3*5 = -15. Next, add c to the previous result, so -15+1=-14. This gives y=-14

15x + 8 = 53

15x = 53-8 = 45

x = 45/15 = 3

1. We currently have 80% of the original price and aim to find 100%.

2. We know that 80% is equal to £29.40.

3. Dividing £29.40 by 80 gives the value of 1% which is £0...

1. We aim to factorise the numerator. This would give 6c(c^2 + 5).

2. We then factorise the denominator. This would give 3(c^2 + 5).

3. Since (c^2 + 5) is present in b...
