Question

Just please answer it for me I really need help What sentence represents the number of points in the problem below? A test is worth 50 points. Multiple-choice questions are worth 1 point, and short-answer questions are worth 3 points. If the test has 20 questions, how many multiple-choice questions are there? O A. The number of multiple-choice question points minus the number of short-answer question points is 20. O B. The number of multiple-choice question points plus the number of short-answer question points is 20

Answer 1

so B

Explanation:

the equation would be

x+3y=50

x = multiple choice

y = short answer

then solve for x and y when x+ y=20

Answer 2

Correct answer is C.

Explanation:

m + 3s = 50

the total number of questions is 20. since the paper is made of only multiple choice and short answer questions, the sum of the multiple choice and short answer questions should be 20.

since multiple choice is 'm' and short answer is 's'

then m + s = 20

but theres no option for that

if we take the number of points

points for 1 multiple choice question - 1

then points for m number of multiple choice questions = 1 * m = m

points for 1 short answer - 3

then points for s number of short answer question = 3 * s = 3s

then total number of points = m + 3s

and the total number of points = 50

therefore

m + 3s = 50

this is the correct answer C.
