The dance team traveled to a competition and traveled in two vans. The first van transported 2 adults and 5 students and cost $7
Shtirlitz [24]

Answer: $9

Step-by-step explanation:

Let the cost for adults be a

Let the cost for students be b.

The first van transported 2 adults and 5 students and cost $77. This will be:

2a + 5b = $77

The second van transported 2 adults and 7 students and cost $95. This will be:

2a + 7b = $95

2a + 5b = 77 ...... equation i

2a + 7b = 95 ........ equation ii

Subtract equation ii from I

-2b = -18

b = 18/2

b = $9

An student cost $9

Put the value of b into equation i

2a + 5b = 77

2a + 5(9) = 77

2a + 45 = 77

2a = 77 - 45

2a = 32

a = 32/2

a = 16

An adult costs $16

PLEASE, IT IS URGENT!!!!!!!!!!!!!!!!
sasho [114]
Convert the timing into hours only:
11:15  = 11.25h
 9:45  = 9.75h
11:45 = 11.75h
 7:45  = 7.75h
10:45 = 10.75h

To find the average, we need to find the middle of these timing:
11.25 + 9.75 + 11.75 + 7.75 + 10.75 = 51.25

51.25 ÷ 5 = 10.25h = 10:15 am

------------------------------------------------------------------------
Answer: The average time it docks is 10:15 am.

PLEASEE HELP MEEE I DONT UNDERSTAND IT
Lorico [155]
<h2>Answer:</h2><h3>The answer should be, "The Least Frequency is at 13 Years."</h3><h3>-</h3><h3>The range should be 4, so that can't be it, and from the graph the frequency does not increase, it just goes down then back up.  Just based off the graph, it should be the 2nd choice :)</h3>

Which of the following coordinates belong in the box?
Lera25 [3.4K]
Since the distance from the two known coordinates are known, you can find the slope of the line (for lack of a better word) to work backwards. there is a +5 unit gap between -21 and -16, so the next number would be -26. So, without havint to do any more work, the answer is B.
