The 4 Pack is the better value ;)
Answer:
x = 5/3
Step-by-step explanation:
4x= x + 5
3x=5
x = 5/3
(2/3)x^2 -6x + 15 = 0
Using the quadratic formula:
x = [-b +-sq root(b^2 - 4 *a*c)] / 2a
x= [--6 +-sq root(36 -4*(2/3)*15] / 2*(2/3)
x= [6 +-sq root 36 -40] / (4/3)
x1 = 4.5 + (2i / (4/3))
x1 = 4.5 + 1.5i
x2 = 4.5 - (2i / (4/3))
x2 = 4.5 - 1.5i
Answer:
First on is £12 cuz when the mile is 0, it starts with 12.
Second is £28 (I think)
