Atest 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?

a. s for short answer, t for test
b. m for multiple choice, s for short answer
c. t for test, q for questions
d. p for points, m for multiple choice

There are 5 multiple choice questions

Step-by-step explanation:

Let

m ----> the number of multiple choice  in a test

s ----> the number of short answer  in a test

we know that

The test has 20 questions

so

----> equation A

A test is worth 50 points

so

----> equation B

Subtract equation A from equation B

Find the value of m

therefore

There are 5 multiple choice questions

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
