Step-by-step explanation:
We started with one small box. Then we added a box on the side to make it twice as long. Then we added boxes on top to make it twice as tall. Then we added boxes behind it to make it twice as long. That gave us 8 of the small boxes.
Then we multiplied 8 boxes by 24 staplers in each box and got 192 boxes.
Answer:
The number of multiple choice plus the number of short answers is 25
Step-by-step explanation:
2x+4y=80
x+y=25
y=-x+25
2x+4(-x+25)
2x-4x+100
-2x+100=80
-2x=-20
x=10
y=15
Answer:
The answer to your question is
a) Poster width = 3 in
lenght = 9 in
b) banner
width = 2 in
lenght = 10 in
Step-by-step explanation:
a) For the poster
width = x
lenght = 3x
Perimeter of a rectangle = 2base + 2 height
= 2(x) + 2(3x) = 24
2x + 6x = 24
8x = 24
x = 24/8
x = 3
width = 3 in
lenght = 3(3) = 9 in
b) For the banner
width = y
lenght = 5y
Perimeter of a banner = 2 base + 2 height
2 (y) + 2(5y) = 24
2y + 10y = 24
12y = 24
y = 24/12
y = 2
width = 2 in
lenght = 5(2) = 10 in
