Let, Number of multiple choice = x
Number of short answer question = y
Now, x + y = 20
& 3x + 11y = 100
Multiply 1st equation by 3, and subtract from eq,2,
3x + 3y = 60
After subtraction,
8y = 40
y = 40/8
y = 5
Now, substitute in eq (1),
x + 5 = 20
x = 15
In short, There are 15 Multiple choice & 5 short answer questions
Hope this helps!
Answer:
X=8
The three lines means that IN and AT are equal so IN must equal 26. 2(8)=16 and 16+10=26
The answer is C an example is 20% of $20 is 4, so you would lose the zero and double the 2 to get 4
