85C - 170A = 306 ---------- (1)
255 + 85B = 714 ------------(2)
(1) + (2):
85C + 85A + 85B = 1020
Divide by 85 through:
A + B + C = 12
The total of A, B ad C is 12.
-------------------------------------------------------------
Find average :
-------------------------------------------------------------
The average of A, B and C is 12 ÷ 3 = 4
-------------------------------------------------------------
Answer: The average of A, B and C is 4.

The answer is 1561 in^2
The lateral surface area formula of a cylinder is LA = 2 pi r h
We are given
r=14.6 in
h=16.8 in
pi=3.14
LA = 2 * 3.14 * 14.8 * 16.8 about 1561 in^2
Answer: The answer is 1,037. You did good with the first three steps but you need to do the same for the last step, because you have 21 you have to find how many times 3 goes into it, which would be 7, and that gives you your full answer of 1,037.
a) Let f be the cost of each ticket. We know that 2 tickets cost a total of $24.95, so therefore we have this equation:
2f = 24.95
b) Solve this equation by dividing both sides by 2:
f = 12.475
This value isn't possible with money so to make it realistic, we'll round to the nearest cent:
f = $12.48
c) We're ordering one more ticket, so we'll just add f to our total cost:
64.50 + f
= 64.50 + 12.48
= $76.98
Answer:
Final answer is approx 6.644 years.
Step-by-step explanation:
Given that a company sold 5.75 million motorcycles and 3.5 million cars in the year 2010. The growth in the sale of motorcycles is 16% every year and that of cars is 25% every year.
So we can use growth formula:
Then we get equation for motorcycles and cars as:
Now we need to find about when the sale of cars will be more than the sale of motorcycles. So we get:
Hence final answer is approx 6.644 years.
