Answer:
x=-4.5
Step-by-step explanation:
In the given triangle, Two sides are divided into equal part.
It means D and E is mid point of AB and AC.
Mid-point theorem: The line joining the mid points of sides of a triangle then line (DE) parallel to BC and DE is half of BC.
In the given figure, (Attachment)
DE = 3x+4
BC = 4x-1
[mid-point theorem]
Hence, The value of x is -4.5

we know that Bob can do the whole job in 14 hours, how much of the work has he done in 1 hour only? well since he can do the whole lot in 14 hours in 1 hour he has only done 1/14 th of the job.
we know that James can do it in 18 hours, a bit slower, so in 1 hour he has done only 1/18 th of the job.
let's say it takes both of them working together say "t" hours, so in 1 hour Bob has done (1/14) of the work whilst James has done (1/18) of the work, the whole work being t/t or 1 whole, so for just one hour that'd 1/t done by both Bob and James.
