Here's our data:
15 questions total
Total number of points: 100
Spelling questions are worth 5 and represented by x
Vocab questions are worth 10 and represented by y
Therefore:
x+y=15
5x + 10y= 100
So:
x+y=15
x= 15-y
5x +10y =100
5(15 -y) +10y =100
75 -5y +10y =100
75 +5y = 100
5y=25
y=5
x +y=15
x+5=15
x=10
There are 10 spelling questions and 5 vocab questions
M is 6 and B is -2 (if you need the equation it is y=6x-2)
