Step-by-step explanation:
every single flipping may two results, head or tail.So last one has equal chance.
ven numbers always end with a digit of 0, 2, 4, 6 or 8.
2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 are even numbers.
Odd numbers always end with a digit of 1, 3, 5, 7, or 9.

5.5 = x
c(x)=x-2
3.5 = x-2
Add 2 to each side
3.5+2=x-2+2
18km/[unit of time]
v (speed) = d/t
v = 198/11
v = 18
To find the answer you just have to solve 4(x-3)
4(x-3)=4x-12
So B or 4x-12 is correct.
