Answer:
6x - 5 = 67
6x = 72
x = 12
Step-by-step explanation:
setting the equation and variable x to the number
6 times the number and its difference to five is 67
plus five on both sides
divide both sides by 6
answer is 12
List the multiples of both 12 and 9:
12, 24, 36, 48, 60
9, 18, 27, 36, 45
The lowest common multiple is 36.
This will make the fixtures and bulbs equal.
This means they bought 3 packages of light figures 3 x 12 = 36)
And bought 4 packages of bulbs ( 4 x 9 = 36)

Answer:
For many(n) tickets, the average payoff is 0.5n, in which n is the number of tickets.
Step-by-step explanation:
1/1000 chance of winning.
This means that there is an 1/1000 probability of you earning $500.
1 - 1/1000 = 999/1000 chance of losing.
In this case, you earn nothing.
What is your average payoff from many tickets
![A = \frac{500*1}{1000} + \frac{0*999}{1000} = \frac{500}{1000} = 0.5](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B500%2A1%7D%7B1000%7D%20%2B%20%5Cfrac%7B0%2A999%7D%7B1000%7D%20%3D%20%5Cfrac%7B500%7D%7B1000%7D%20%3D%200.5)
Your average payoff from a ticket is 0.5. So for many(n) tickets, the average payoff is 0.5n, in which n is the number of tickets.
