<span>1st train DATA:
rate = 50 mph ; time = x hrs ; distance = rt = 50x miles
2nd train DATA:
rate = 55 mph ; time = (x-(1/2)) hrs ; distance = rt = 55(x-(1/2)) miles
Equation:
distance = distance
50x = 55(x-(1/2)
50x = 55x - (55/2)
-5x = -55/2
x = 11/2
x = 5 1/2 hrs (time at which the 2nd train overtakes the 1st train)

Answer:
2, 6, 18, 54..
Step-by-step explanation:
2, 6, 18, 54...
2 x 3 = 6
6 x 3 = 18
18 x 3 = 54
54 x 3 = ...
K or l will be 151 degrees.
j and m are equal to each other, giving you x=1, substitute this in to get j and m equal 29 degrees. k or L are opposite angles meaning they add up to 180 when added to j and m so j+l=180 or m+k=180
