Liliana and Marcus are playing a word game. Liliana spells a word incorrectly and loses 18 points. Then Marcus spells a word correctly and has the opposite score. Which is the correct way to represent “the opposite of Liliana’s score is equal to Marcus’s score”?

Question

Negative 18 = 18
Negative (negative 18) = negative 18
Negative (18) = negative 18
Negative (negative 18) = 18

Answer 1

The correct way to represent “the opposite of Liliana’s score is equal to Marcus’s score” is:

Negative (negative 18) = 18

This is because the opposite of Liliana's score (-18 points) is 18 points (since the opposite of a negative number is positive). Therefore, the equation states that taking the negative of Liliana's score (which is -18) results in 18, which corresponds to Marcus's score.
