Step-by-step explanation:
Remmeber yo can do antyhing to an equation as long as you do it to both sides
9x>270
divide both sides by 9
x>30
B/4<4
times both sides by 4
B=16
Y/5≤8
times both sides by 5
Y≤40
5c≥125
divide both sides by 5
c≥25
Answer:
10 feet
Step-by-step explanation:
The formula for the Perimeter fo a rectangle
= P = 2L + 2W
Where:
L = Length
W = Width
From the question
P = 80 feet
W = 30 feet
Hence:
80 = 2L + 2(30)
80 - 2(30) = 2L
80 - 60 = 2L
20 = 2L
L = 20/2
L = 10 feet
Hence, the length of the fenced area = 10 feet
Answer:
D
Step-by-step explanation:
Answer: You receive 14x+45 dollars for each gallon of cider that you sell.
Step-by-step explanation:
Given: For selling each gallon of cider, the company receives x dollars.
You receive = Remaining amount
i.e. You receive $(Selling price - x)
By selling 15 gallons in 15x+45 dollars, you have received (15x+45)-x dollars
i.e. You received 15x+45-x dollars
i.e. You received 14x+45 dollars.
Hence, you receive 14x+45 dollars for each gallon of cider that you sell.
