D = vt
Distance traveled by train
d = 55t
Distance traveled by plane
d = 285t
Total distance
d = 1020
So, you do:
distance traveled by plane + distance traveled by train = total distance
(55t) + (285t) = 1020
Solve for t
t = 3 hours
t is the time traveled by each so 3 hrs traveled by train and 3 hrs traveled by plane
Total time = 3 + 3 = 6 hours
Three consecutive numbers can be written as x, x+1, and x+2, but they also can be written x, x-1, and x-2 where x is the biggest number.
sum means adding... so
combine like terms and solve for x!
The median is 4 because 2 x’s out 9, 3 x’s out 7, 3 x’s out 5, and 4 is the only remaining number.
Did you find the answer? I could use the help with it too.
Explanation:
Abraham Lincoln recognized the importance of the city on a 200-foot bluff just above Colorado river. He said, "Vicksburg is the best approach, the war could never be decided to bring to a close until another key is in our wallet." trying to capture Vicksburg would break the Trans-Mississippi confederate states from the east of the Mississippi as well as open the waterway to northern congestion along its total duration.
