Answer:
2 multiple choice problems
Step-by-step explanation:
the equations will be...
x=true/false questions
y=multiple choice problems
x+y=30
3x+8y=100
5y=10
An equation is formed of two equal expressions. The number of multiple-choice questions in the test is 2.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The number of true/false question be represented by x, while the number of multiple-choice question be represented by y. Therefore, the total number of questions can be written as,
x + y = 30
solving for y,
y = 30 - x
Now, for the total points in the test, we can write,
3x + 8y = 100
3x + 8(30-x) = 100
3x + 240 - 8x = 100
-5x = -140
x = 28
Substitute the value of x in the first equation, we will get,
x + y = 30
28 + y = 30
y = 2
Hence, the number of multiple-choice questions in the test is 2.
