One day, a person went to horse racing area, Instead of counting the number of human and horses, he instead counted 74 heads and 196 legs. Yet he knew the number of humans and horses there. How did he do it, and how many humans and horses are there?

One day, a person went to horse racing area, Instead of counting the number of human and horses, he instead counted 74 heads and 196 legs. Yet he knew the number of humans and horses there. How did he do it, and how many humans and horses are there?

**Let's assume that HM = Human and**

**HR = HorseHM + HR = 74**

**2HM + 4HR = 196**

**(2HM + 4HR) - (2 HM + 2HR) = 196 - 148**

**2HR = 48**

**HR = 24**

**HM + (24) = 74**

**HM = 74 - 24**

**HM = 50**

So, the solution is 24 horses and 50 humans.

So, the solution is 24 horses and 50 humans.

What place in this world can have their temperatures Fahrenheit and Celsius equal?

What place in this world can have their temperatures Fahrenheit and Celsius equal?

**F = 1.8C + 32**

x = 1.8x + 32

x - 1.8x = 1.8x + 32 - 1.8x

-0.8x = 32

-8x = 320

-x = 40

x = -40

The only place that might be -40 degrees cold must be Anartica.

x = 1.8x + 32

x - 1.8x = 1.8x + 32 - 1.8x

-0.8x = 32

-8x = 320

-x = 40

x = -40

The only place that might be -40 degrees cold must be Anartica.
