The first question is square or rectangle
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.
Answer:
a
Step-by-step explanation:
Perimeter is the sum of the two lengths plus the sum of the two widths.
Divide the perimeter in half and that is the sum of one length and one width.
27/2 = 13.5
The ratio is 2:1, add the ratio: 2 +1 = 3
Divide the sum by 3:
13.5/3 = 1.5
Multiply that the each portion of the ratio:
4.5 x 2 = 9
4.5 x 1 = 4.5
The length is 9 inches
The width is 4.5 inches
