Answer:
History of mathematics
Several civilizations — in China, India, Egypt, Central America and Mesopotamia — contributed to mathematics as we know it today. The Sumerians were the first people to develop a counting system. Mathematicians developed arithmetic, which includes basic operations, multiplication, fractions and square roots. The Sumerians’ system passed through the Akkadian Empire to the Babylonians around 300 B.C. Six hundred years later, in America, the Mayans developed elaborate calendar systems and were skilled astronomers. About this time, the concept of zero was developed.

Answer:
I'm pretty sure it's 4
Step-by-step explanation:
association property of addition involves well addition and that's what it shown in y+0=y
I think 3.16 I said I think
Y = 7.5*200 +500
y = 1500 +500
y = 2000
2000 gallons are in the pool 200 minutes after the pump is turned on.
