Area=legnth times width
width=1/5
area=1/5 times width
area=4
4=1/5 times legth
multiply both sides by 5/1 to clear fraction (since 1/5 times 5/1=5/5=1)
remember ou can do anything to an equaiton as long as you do it to both sides
20=1 times legnth
20=legnth
answer is legnth==20 m

Answer:
Mary's ticket was less than the original price by 12 percent
Step-by-step explanation:
1. Let's calculate the 20% discount price Mary received:
75 - 0.2 * 75 = 75 - 15 = $ 60
The discounted price is $ 60
2. Let's calculate the 10% service fee to the discounted price:
60 + 0.1 * 60 = 60 + 6 = $ 66
The price including the service fee is $ 66
3. Finally, let's calculate the less percentage than the original price:
Let's use the Direct Rule of Three, this way:
Price Percentage
75 100
66 x
**************************
75x = 66 * 100
75x = 6,600
x = 6,600/75
x = 88
Less percentage = 100 - 88 = 12%
Mary ticket was less than the original price by 12 percent

Answer:
D.
Step-by-step explanation:
I am assuming they are not allowing graphing calculators for this, which is kind of wacky, if you ask me.
Anyway, the greater or equal to can technically be used interchangeably, so it looks like this:
y > 2x --> y = 2x
And so, with that equation, the sign just tells you what section of the graph is included. In this case, everything above the line.
