What system of equations would you use to solve the problem below? A test is worth 100 points. Multiple-choice questions are worth 3 points and
short-answer questions are worth 5 points. If the test has 28 questions, how
many multiple-choice questions are there?
A. m + s = 8
3m + 5s = 128
B. m + s = 100
3m + 5s = 28
C. m + s = 28
3m + 5s = 100
D. m. $ = 28
3m. 5s = 100

Step-by-step explanation:

here's the solution,

let number of multiple Choice questions be m

and number of short answer questions be s

1. total number of questions = m + s = 28

( total multiple choice questions + total short answer questions )

2. total points = total points of multiple Choice questions + total points of short answer questions

=》3m + 5s = 100

so, the required equations are :

=》m + s = 28

=》3m + 5s = 100

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
