They are abstract "word" problems, offered for the purpose of giving the
student of high school mathematics valuable practice in the application
and manipulation of the concept of "percent".
Often, some time spent in solving practice-examples such as these can
lead to the phenomenon known as "learning", whereby the student comes
to know, understand, and possess competence in a topic where he or she
was previously ignorant and incompetent.
It is important to realize that the practice is the vital component in the process,
whereas the answers alone have no value at all.
Since you don't provide the coordinates of the point W, I will help you in a general form anyway. In the Figure below is represented the segment that matches this problem. We have two endpoints U and V. So, by using the midpoint formula we may solve this problem:

Therefore:

So we know
but we also must know 
Finally, knowing the points U and W we can find the endpoint V.
Answer:
Part B: is -60 divided by -10
Part C: is The number of increments is positive.
Part D: is -1 times 60 / -1 times 10
Part E: is Any number divided by itself is 1. In the expression -1 times 60, the -1s in the numerator and the denominator cancel each other out to give the result 60/10, or 6
Part F: is There are 6 increments of -10 feet in -60 feet.
Part G is: copy and paste -10 feet 6 times
Part H: is -60 / 4 increments
Part I: is there is one negative number in the expression, so the solution will be negative. There isn't a -1 in the denominator to cancel out the -1 in the numerator.
Part J: is -60 /4 =-15 Alex’s elevation change in each increment was -15 feet.
Step-by-Step Explaination: I did the test.
The main thing is rise/run. y=mx+b that is the formula for slope
Answer:
Alternate exterior angles formed in the parallel lines are EFH and DCA.
pls give brainliest for the answer
