Answer:
5 cents
Step-by-step explanation:
So the roulette wheel would have a total of 38 numbers, which means 38 different possible cases. Since you are allowed to bet on 5 numbers, the chance to win this is 5 out of 38 and to lose this is 33 out of 38.

Answer:
x=2
Step-by-step explanation:
implifying
12x + 8 = 32
Reorder the terms:
8 + 12x = 32
Solving
8 + 12x = 32
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 12x = 32 + -8
Combine like terms: 8 + -8 = 0
0 + 12x = 32 + -8
12x = 32 + -8
Combine like terms: 32 + -8 = 24
12x = 24
Divide each side by '12'.
x = 2
Simplifying
x = 2
