Rap:

Add and subtract both relations and you get
X+Y=5 and X-Y=1
Then it becomes apparent that X=3 and Y=2

Add the equation to give: 10000X + 10000Y = 50000
Divide by 10000 to give: X + Y = 5
Subtract to give: 3502X - 3502Y = 3502
Divide by 3502 to give: X - Y = 1
Therefore: X = 3 and Y = 2

TTH:

Ya, what rap said

Hey Mark you are looking good! New hair style?

Hi Jove, I have missed you too. Nice set of wheels you have chosengo for it.

A local farmer knows that 20 of his hens, housed in 3 coops, will hatch 30 eggs in 18 days.

How long will it take 30 hens, housed in 4 coops to hatch the same number of eggs

Hellooooooooooo! Who turned the lights out!

Five A2K'ers entered a contest to guess how many balls were in a bowl.
Rap guessed 45, Jove guessed 39, Mark guessed 49, Mismi guessed 50, and TTH guessed 47.

One was off by 6, one by 5, one by 2, and one by 4.

One was right; who was it

Hatch the same # of eggs? The same amount of time as the 20 hens.

Oh boy; that was some partywhat day is it?

TTH:

The lady is totally correct; you can't shorten the process of egg-hatching by increasing the number of chickens.

Hey buddy, I didn't know you were a mathamagician!

I don't see any way of doing this aside from working through it. We know that the number is at most 6 away from other numbers. This immediately rules out 39, 49, and 50 which are 10 and 11 away from each other.
It also rules out 47 that is 8 away from 39. That leaves 45. 45 is 6 away from 39, 5 away from 50, 4 away from 49, and 2 away from 47. So there are 45 balls in the bowl and Rap guessed correctly.

You could have answered it by noticing that all of the guesses were odd but one (50), and that all of the degrees by which they were wrong were even but one (off by 5). To get an even number from an odd number, you have to subtract or add another odd number, and there's only one odd number available. So just look for an answer that was five less than 50, given that 50 was on the higher end of things.

A bug crawls at a speed of 21cm per hour towards a vegetable patch. After eating its fill it returns, over exactly the same distance, at only 7cm per hour.

Not including the eating time, what is the bug's average speed over the entire journey

At first glance it seems that you could just add 21 + 7/2=14....but I don't think so. How about 21(1 hour) + 21(7 x 3hours)=42/4=10.5 cm per hour?

[size=7]let d be the distance in cm to the vegtable patch

then 21*t1=d & 7*t2=d
2d=21*t1+7*t2=3*7*t1+7*t2
if t0=t1+t2
then
2d=7*(2*t1+t0)
average speed then is Va & Va*t0=2d
so
Va*t0=7*(2*t1+t0)
(Va-7)*t0=14*t1=2/3*2d
Va*t0-7*t0=2/3*2d
2d-7*t0=2/3*t0
6d-21*t0=2*t0
solve for t0
t0=4d/21 hr
since Va*t0=Va*4d/21=2d
solve for Va
Va=2d*(21/4d)=21/2=10.5 cm/hr

It took all that to get this
21(1 hour) + 21(7 x 3hours)=42/4=10.5 cm per hour?

Bug's Life

At first glance it seems that you could just add 21 + 7/2=14....but I don't think so.

How about 21(1 hour) + 21(7 x 3hours)=42/4=10.5 cm per hour?

Speed is distance over time. If he travels 21cm to the vegetable patch then it will take him 1 hour to get there (at 21cm/hour) and 3 hours to get back (at 7cm/hour). He/She will have traveled 42cm (21 x 2) over 4 (1 + 3) hours so his average speed is 10.5cm/hour.

Rap:

let d be the distance in cm to the vegtable patch

then 21*t1=d & 7*t2=d
2d=21*t1+7*t2=3*7*t1+7*t2
if t0=t1+t2
then
2d=7*(2*t1+t0)
average speed then is Va & Va*t0=2d

so

Va*t0=7*(2*t1+t0)
(Va-7)*t0=14*t1=2/3*2d
Va*t0-7*t0=2/3*2d
2d-7*t0=2/3*t0
6d-21*t0=2*t0
solve for t0
t0=4d/21 hr
since Va*t0=Va*4d/21=2d
solve for Va
Va=2d*(21/4d)=21/2=10.5 cm/hr

Rap, that is so good, I'm gonna get it printed out and framed for the den; if you have no objections.

I can see that and look forward to reading moreSorry, I don't know William; is he related to Bill Shakespeare?

You and Rap pass by a standard coin operated (US) vending machine and you decide to get a candy bar. The price is US \$0.95 but after checking your pockets you only have a dollar (US \$1) and the machine only takes coins.

You turn to Rap and have this conversation.

You: Hey, do you have change for a dollar?

Rap: Let's see... I have 6 US coins but, although they add up to US\$1.15, I can't break a dollar.

You: Huh? Can you make change for half a dollar?

Rap: No.

Rap: Nope. And before you ask I can't make change for a dime or nickel either.

You: Really? And these 6 coins are all US government coins currently in production?

Rap: Yes.

You: Well can you just put your coins into the vending machine and buy me the candy bar, and I'll pay you back?

Rap: Sorry, I'd like to but I can't with the coins I have.

What six coins does Rap have

Mark:

CHANGE
4 dimes
1 quarter
1 fifty cent piece

They all add up to US\$1.15 and he doesn't have change for a dollar, US\$0.50, US\$0.25, US\$0.10, or US\$0.05.

Also, and here's a trick; he can't buy the candy bar for US\$0.95 because a typical US vending machine doesn't take 50 cent coins -- only quarters and below.

TTH enquired about the whereabouts of Thoh. May I suggest you try:

The Metropolitan Correctional Center (MCC) in Chicago, Illinois this is an administrative facility designed to house Federal prisoners of all security levels, including both male and female offenders appearing before Federal courts in the Northern District of Illinois.

MCC Chicago is located in downtown Chicago, at the intersection of Clark and Van Buren Streets.

You're sitting in a car that's not moving, along with a helium-filled balloon, which is resting up against the car's ceiling somewhere near its middle. The driver hits the gas and the car accelerates forward, throwing you back into your seat.

What happens to the balloon

What happens to the balloon ?

It moves forward, and typically hits me in the back of the head much to the amusement of my children.
