Answer:
12 multiple choice questions
Step-by-step explanation:
The system of equations is:
m + t = 19 (quantity of questions)
6m + 4t = 100 (point value)
We use elimination to solve.
Multiply everything in the first equation by 4.
4m + 4t = 76.
subtract that from the second equation.
2m = 24
Divide both sides by 2.
m = 12
Answer:
Step-by-step explanation:
Let x be the number of true or false questions.
Let y be the number of multiple choice questions
Total questions = 19
x + y = 19 ---------------(i)
Total points = 100
4x + 6y = 100 ---------------(ii)
Multiply equation (i) by (-4).
(i)*(-4) -4x - 4y = -76
(ii) 4x + 6y = 100 {Now add. thus x will get eliminated}
2y = 24
y = 24/2
y= 12
There were 12 multiple choice question
