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

Step-by-step explanation:
She has 3 skirts and that is the least amount of clothing and you need that to make a full outfit.
Answer:
-3
Step-by-step explanation:
First you subtract the first equation from the second one and you get:
3x + 3y = 3
x + y = 1
y = 1 - x
Then you use it on the first equation
888x + 889 (1 - x) = 890
888x + 889 - 889x = 890
-x = 1
x = -1
y = 1 - x
y = 1 - (-1) = 2
Now that you have those two numbers, we have to subtract the value of x from y:
x - y
-1 - 2 = -3
