Answer:
First mechanic: 12.8 hours & Second mechanic:12.8 hours
First mechanic made 832$ & Second mechanic made 768$
Hope this is right. If not I apologize and please let me know:)
Step-by-step explanation:
First you would do 65+60=125. You do this to find how much they charge together. Then you would take the amount of money they make and divide that from 125: 1600/125=12.8. Now that you have 12.8 you would plug that in for each mechanic: 65 times 12.8=832 and 60 times 12.8=768. Now you have the amount of money each mechanic made and the amount of hours they worked.
Answer:
do u still need help. I can help
1st disribute .4 through the parentheses.
.4 (.3x-1)=2+.75x
.12x-.4=2+.75x
subtract .12x from each side
-.4 = 2 + .63x
subtract 2 from each side
-2.4 = .63x
Divide each side by .63
-3.81 = x
Answer:

Step-by-step explanation:

First, we need to make the demoninators the same so we times 4 by 5 and whatever we do to the bottom, we do to the top, and 5 by 4.



demoninator now doesn't change unless you're multiplying or dividing.
What you're looking at in this image are two alternate exterior angles.
Alternate exterior angles, are, essentially, exterior angles of a transversal that runs through two parallel lines. These angles are on alternating sides. These angles, assuming the lines are parallel, must be equal.
There's a proof behind why these angles are equal, but I won't bore you with the specifics as the question doesn't require it.
So - we know that these two angles must be equal to prove that the lines A and B are parallel. Knowing this, we can write an equation:
5x + 20 = 3x + 60
<u>Subtract 20 from both sides:</u>
5x + 20 - 20 = 3x + 60 - 20
5x = 3x + 40
<u>Subtract 3x from both sides:</u>
5x - 3x = 3x - 3x + 40
2x = 40
x = 20
