If you would like to know how many gallons remain to be used, you can do this using the following steps:
lost: 2% of 280 gallons = 2% * 280 gallons = 2/100 * 280 = 5.6 gallons
280 gallons - 5.6 gallons = 274.4 gallons
The correct result would be 274.4 gallons.

13x + 5 = 83
-5 -5
13x =78
/13 /13
x = 6
(9.)
0.7 , 0.9 , 1.6 , 2.3 , 2.5
median = 1.6
The coordinates of the midpoint are just the average of the endpoint coordinates ...
x-mid is the average of the end-x's, and y-mid is the average of the end-y's.
P. x = 0, y = 8
Q. x = 4, y = 2
'x' of the midpoint is the average of 0 and 4 = (1/2)(0 + 4) = 2
'y' of the midpoint is the average of 8 and 2 = (1/2)(8 + 2) = 5
The midpoint is (2, 5) .
That's choice-'c'.
Answer:
D
Step-by-step explanation:
elves in 1000 years = elves now x (rate of increase)^time
elves increase every century. there are ten years in a century. thus time = 1000/100 = 10 years
144 x (3)^10 = 8,503,056 elves
