Answer:
C. The number of multiple-choice questions plus the number of
short-answer questions is 15.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the number of multiple-choice questions
y is the number of short-answer questions.
Multiple-choice questions are worth 2 points, and short-answer questions are worth 5 points.
This means that:

The test has 15 questions.
This means that:
.
Which means that option C is the correct answer.
Do 540 ÷ 45 as you're first step. Then multiply that by 3/4.
540÷4= 12.
<h2><em>
12 × 3/4 = 9. Awnser</em>: 9</h2>
One of the numbers are negative
Remember this... a negative divided by a positive will result in a negative and a negative divided by a negative will result in a positive, the same goes for multiplication
