Abraham Lincoln, gettysburg address begins with the phrase (four score and seven years ago.) He was refering to a period of time that was 87 years long. How many years are represented by a score? is the answer 2 or is it 12.43

Well, if there are 4 scores and seven years in 87 years...

4s+7=87, solve for s

To determine how many years are represented by a score, we need to understand the historical context behind the term "score." In the time of Abraham Lincoln, a "score" referred to a unit of 20 years.

So, if you consider that a score represents 20 years, the phrase "four score" in Abraham Lincoln's Gettysburg Address would mean 4 x 20 = 80 years. Therefore, "four score and seven years ago" would be 80 + 7 = 87 years.

Hence, a score represents 20 years, not 2 or 12.43 years.
