A professor wants to create a test that has 12 true-false questions, 8 multiple-choice questions, and 4 essay questions. She wants the test to be worth 400 points, with
each multiple-choice question worth twice as many points as a true-false question and with each essay question equal to three times the number of points of a
true-false question.
a. Write a system of equations to represent this problem, with x, y, and z equal to the number of points for a true-false, multiple-choice, and essay question,
respectively. Select all the equations that are needed for the system that represents this problem.
O A. y= 3z
O B. y=2x
O C. 12x+ 8y + 4z = 400
O D. x+y+z= 0
O F. x= 2y
O H. x+y+z= 400
O E. z= 2x
O G. x= 2z
O J. z= 3x
O I.
12x+ 8y + 4z = 0
