Let x represent lower level tickets that cost $77
Let y represent upper level tickets that cost $99
Cost equation: 77x + 99y = 247,071
Tickets equation: x + y = 2615
Using the elimination method, multiply the second equation by -77:
77x + 99y = 247,071
-77x - 77y = -201,355
--> 22y = 45,716
--> y = 2,078
Now plug "y" into either equation and solve for "x". I chose the Tickets equation. x + y = 2615 → x = 2615 - y → x = 2615 - 2078 → x = 537
Answer: lower level = 537 tickets, upper level = 2078 tickets.
The answer is Option B
We know that this inequality doesn't require any negative number division, there's no need to switch the ≤'s into ≥'s.
So now, all we have to do is subtract 25 from every number, giving us <u>5≤x≤50</u>
Answer:
4,260 feet below sea level (-4,260 feet)
Step-by-step explanation:
The submarine starts at sea level which should be 0 for elevation. And descending 7 feet per second for 2 minutes which means it went down 840 feet ( 7x60x2). Then 4 feet per second for 3 minutes which is 720 feet (4x60x3). Lastly 9 feet per second for 5 minutes which is 2,700 feet (9x60x5). Then you add up those three totals, 840 + 720 + 2,700 = 4,260. So the elevation is -4,260 feet, or 4,260 feet below sea level
Answer:
There is a 
chance of the spinner landing on red, then three.
Step-by-step explanation:
So the first one has a 
chance, since there are four possibilities.
The second one has a 
chance, since there are three possibilities.
So, we just need to combine them.
Have a nice day. Please mark brainliest!
The answer is 12.58 rounded up it would be 13 so the correct answer is A
