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

its 4 because 2 times 2 is 4, if you double the number two you get four

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
