A100-point test contains a total of 20 questions. the multiple choice questions are worth 3 points each and the short response questions are worth 8points each. a. write a system of linear equations that represents this situation. b. how many multiple choice questions are on the test? c. how many short response questions are on the test? d. if the teacher changed the test to 15 questions, then how many of each type of question would be on the test?

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
