Answer:
6 multiple choice questions and 22 open/extended response questions
Step-by-step explanation:
Let x be the number of multiple choice questions
Let y be the number of open response questions
Thus, we have a system of equations:
2x+4y=100
x+y=28
Solve bottom equation for desired variable, then plug in to top one:
x+y=28
x=28-y
2(28-y)+4y=100
56-2y+4y=100
56+2y=100
2y=44
y=22
Plug y back into bottom equation to get x:
x+22=28
x=6
So there are 6 multiple choice questions and 22 open/extended response questions.
They won 18.7 or 19 games if rounded up
Answer:
The first two is x=60
Step-by-step explanation:
1.5/90 = 1/x
1.5x = 90 x 1
1.5x/1.5 = 90/1.5
x = 60
Answer: the answer would be Y
