Answer:
<h3>#1</h3>
<u>Rectangle area:</u>
<u>Given:</u>
<u>Find w:</u>
- 12w = 300
- w = 300/12
- w = 25 ft
<h3>#2</h3>
<u>Perimeter is the sum of side lengths:</u>
P = 2 1/4 + 5 2/5 + 5 17/20 =
2 + 5 + 5 + 1/4 + 2/5 + 17/20 =
12 + 5/20 + 8/20 + 17/20 =
12 + 30/20 =
12 + 1.5 =
13.5 ft
<h3>
#3</h3>
- Cost of a shirt = $19.99
- Number of shirts = 6
<u>Total cost:</u>
X = girls
y = boys
z = students in the bus
x + y = z
x + y = 36
total girls = 2 * total boys
x = 2 * y
2y + y = 36
3y = 36
y = 12
x = 2y = 24 (B)
