Create a a system of 2 equations: 2x + y = 27 and 2y + x = 9, with x being the first number and y being the second. solve for the two variables and you'll get the first number is 15 and the second is -3.

What is pi???????????????
Kipish [7]

Answer:

The ratio of a circle's circumference to its diameter

In other words: all the way around a circle divided by all the way across it.

The symbol is π (pi)

No matter how large or small the circle, its circumference is always π times its diameter.

π = 3.14159265358979323846... (the digits go on forever without repeating)

A rough approximation is 22/7 (=3.1428571...), but that is not accurate.
