Answer:
1st mechanic:20hours
2ndmechanic:15hours
Step-by-step explanation:
1stmechanic:20hours=20x95
=$1900
2nd mechanic:15hours=15x110
=$1650
total=<u>$1900+$1650</u>
=$3550
The midpoint is (5, ¹/₂).
<h3>
Further explanation</h3>
The midpoint is the coordinates of a point right in the middle of a line segment or two endpoints.
The Midpoint Formula 
So, abscissa and ordinate of the midpoint are the averages of both endpoints. i.e., (x₁, y₁) and (x₂, y₂).
Given (x₁, y₁) = (5, 4) and (x₂, y₂) = (5, -3).
Let's calculate the midpoint.



We get the midpoint between the two endpoints, that is, (5, ¹ / ₂).

Step-by-step explanation:
So the answer for 33+45+78 is 156.
If you want to check that, you can use inverse operations, so subtract.
156-78=78. (Check 78)
78-45=33 (Check 45 and 33)
Well, now it's checked because we used all the factors of the equation!
