Hey Chandler! 

 

It's simple.

 

Look,

999,999,999

666,666

333

 

Are all divisible to 3.

 

And when added togther the sum is STILL DIVISIBLE BY 3!

 

So when you add 1,

It is not divisible by three

 

 

Then you willl just have a remainder of 1!

When I split the cost of a video game equally with 4 friends, we each pay $12.00. How much more do each of us pay if I split the cost equally with only 3 friends?

This is simple as well...

 

If there is 4 people and each pay $12...

 

12*4= $48 

 

So $48 is the total cost of a video game.

 

If three people are paying for the game...

 

 

48/3=16

 

But it is asking how much MORE so..

 

16-12= 4

5040 minutes  =   5040/60 = 84 hours =  84/24= 3 days 12 hours     = Tuesday at 5 AM

5040/60 = 84 hours

84/24 = 3.5 days

 

5pm Frid+half a day =  5am Saturday

5am sat + 3 days = 5am Tuesday

 

Open on Tuesday   (5am)

Hello CDorrell,

 

I can see you have already edited this question twice (after it is anwered) and and each time you have changed it to completely different question.

This is extremely rude.

Please do not edit your questions, or answers, in any way that can be considered rude or inconsiderate, in the future.
