Answer: D
1/2x-1+4=x
1/2x-x=-3
-1/2x=-3
x=6
Option C:
is the slope of the line
Explanation:
The line passes through the points
and 
We need to find the slope of the line.
The slope can be determined using the formula,

Where the coordinates
and
are
and 
Let us substitute the points in the formula
Thus, we have,

Simplifying, we get,

Adding the numerator and denominator, we have,

Cancelling the negative terms, we get,

Thus, the slope of the line is 
Therefore, Option C is the correct answer.
Given that 24 hours is one full day, we can deduce that 2400 hours is 100 days. One full cycle from that time is equivalent to that time therefore, 2400 hours after 5pm is 5pm.
