Answer 1

Search Engine A = 2.09 billion searches.

Search Engine B = 1.43 billion searches.

Explanation:

Engine A + Engine B = 3.52 billion

Search engine A was used to conduct 0.66 billion more searches than search engine B

A = 0.66 billon + B

Hence:

0.66 billion + B + B = 3.52 billion

2B = 3.52 billion - 0.66 billion

2B = 2.86 billion

B = 2.86 billion/2

B = 1.43 billion searches.

A = 0.66 billion + B

A = 0.66 billion + 1.43 billion

A = 2.09 billion searches.

Therefore:

Search Engine A = 2.09 billion searches.

Search Engine B = 1.43 billion
