Answer:
[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1
(5/60 + 3/60)x = 1
(8/60)x = 1 we can reduce 8/60 by dividing out a 4
(2/15)x = 1 x both sides by 15/2
x = 15/2
x = 7 1/2 or 7.5 hours
Because the lines are parallel, 75 is equal to 11x-2
75=11x-2
77=11x
x=7
Multiplicity of a root means, is there that many times.
