.2h=-3.8
h=-19
Answer:

Step-by-step explanation:
Using the midpoint formula,
, we can find the coordinates that represents the position of the ship at noon.
Let
(given on the coordinate plane)
(given also)
Plug in the values into the formula and solve as follows:




Position of the ship at noon is best represented at 
A + s = 480......s = 480 - a
8a + 5s = 2892
8a + 5(480 - a) = 2892
8a + 2400 - 5a = 2892
8a - 5a = 2892 - 2400
3a = 492
a = 492/3
a = 164 <=== there were 164 adult tickets sold
Answer: B. 17
Step-by-step explanation:
4x-3 = 65
Add 3 on both sides
4x = 68
Divide by 4 on both sides
x = 17
BOOM!
4/100= x/4,500
18,000/100= $180x2.5 = $450
