Why did we call a meeting? I was sleeping!
Because Bobby has been gone too long, and I am hungry!!
I am hungry. How long has he been gone??
He said he'd be gone for 6 minutes, but I don't know how long that is.
Well, 6 human minutes is double 1 human minute and 2 dog minutes, so in math that is 2(x+2)=6x.

I just want food.
Starting with the 2(x+2), you just multiply the outside number by the inside numbers. This would be 2x+4.
So we have 2x+4= 6x. Then, we want to get rid of the extra human minutes, which is x. To do this, you subtract 2x from both sides.
Who is here??
So that would be like 2x+4=6x -2x. Then it would be 4=4x. Then, you want X to be alone on its side, so you divide 4 on both sides so you only have x.
Wait, doesn't that mean that 1 dog minute is the same as 1 human minute?? Then Bobby should be home!!
Slide: 3
It's so easy. Double of 1 human minute and two dog minutes is 6 human minutes.
2(x+2)=6x2x+4=6x2x+4=6x-2x4/4=4x/41=x
How'd you know he was here??
I did what y'all did, just faster.

These dogs are trying to figure out how long their owner will be gone in dog minutes.
The dogs use math to figure out that 1 dog minute is the same as a human minute! And their owner comes home before they know it.
