Heh, this is a tricky one. This would get you messed up, thinking it'd be 15 hours. But if they worked together, they would go faster, making it simple subtraction, which means 9-6 = 3.
3 hours. Have a great day.

(2x + 29) + 91 = 180.
This is because they add to form a straight line which is 180 degrees, in other words the angles are supplementary.
2x + 29 = 89 (Subtract 91 from each side)
2x = 60 (Subtract 29 from each side)
x = 30 (Divide 2 from each side)
x = 30
The answer is B

Answer: 1.3</h3>
========================================
Work Shown:
The two points we have are and
Apply the distance formula
-------------------------
A shortcut is possible by subtracting the y coordinates of the two points, and making the result positive through the use of absolute value.
So we either say
|y1-y2| = |1.2-2.5| = |-1.3| = 1.3
or,
|y2 - y1| = |2.5 - 1.2| = |1.3| = 1.3
We get the same result. This shortcut is valid because the x coordinates of both points are the same.
