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

thats not a system of equations, that is a solution

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
