Aperfect score on a test with 25 questions is 100. each question is worth 4 points. fred got a score of 84 on the test write a division sentence using negative numbers where the quotient represents the number of questions fred answered incorrectly

For this case, the first thing we must do is define a variable.

We have then:

x: number of incorrect answers.

We now write the equation that models the number of incorrect questions.

We have then:

a division sentence using negative numbers where the quotient represents the number of questions Fred answered incorrectly is:

the number of questions Fred answered incorrectly is:
