What is the value of x? Show your work for credit.

Question 12 (Essay Worth 4 points)
B is the midpoint of.
AB=3x
AC=7x5
What is the value of BC? Show your work for credit.
3x = .5 (7x  5)
6x = 7x  5
x = 5
x = 5
AB = 3(5)
AB = 15

Question 13 (Essay Worth 4 points)
M is the midpoint of. Find the coordinates of B given A(2,4) and M(3,1). Show your work for credit.
3 = (2 + x©ü) / 2
6 = 2 + x©ü
x©ü = 8
1 = (4 + y©ü) / 2
2 = 4 + y©ü
y©ü = 2
M (8, 2)

Question 14 (Essay Worth 4 points)
Tallahassee was established as the capitol of Florida because it was between Pensacola and St. Augustine. The distance from Pensacola to Tallahassee can be represented as (3x + 40) miles. The distance from Tallahassee to St. Augustine can be represented as (4x + 5) miles. The distance from Pensacola to St. Augustine is 395 miles. Is Tallahassee the midpoint of Pensacola and St. Augustine? Show your work to support your conclusion.
7x+45=395
7x=350 so x=50
3(50)+40+4(50)+5=395

Question 15 (Essay Worth 4 points)
A scalene triangle is a triangle that has no congruent sides.
1. Use the information given in the triangle below to find AB, BC and AC.
2. Determine if the triangle is scalene or not based on the lengths of the three sides.
Show your work and support your conclusion
A (3,6)
B(6,3)
C(1,1)

I assume that this is a practice exam.
There is no point in my doing it. The idea is that you try and ask us to check your answers and help if you get stuck after seeing what you tried to do.
If I just do the problems, you will not be in any better position to take the exam than you are right now, although I might be. 
Question 12 (Essay Worth 4 points)
B is the midpoint of.
AB=3x
AC=7x5
What is the value of BC? Show your work for credit.
3x = .5 (7x  5)
6x = 7x  5
x = 5
x = 5
AB = 3(5)
AB = 15 
Question 13 (Essay Worth 4 points)
M is the midpoint of. Find the coordinates of B given A(2,4) and M(3,1). Show your work for credit.
3 = (2 + x©ü) / 2
6 = 2 + x©ü
x©ü = 8
1 = (4 + y©ü) / 2
2 = 4 + y©ü
y©ü = 2
M (8, 2) 
Question 14 (Essay Worth 4 points)
Tallahassee was established as the capitol of Florida because it was between Pensacola and St. Augustine. The distance from Pensacola to Tallahassee can be represented as (3x + 40) miles. The distance from Tallahassee to St. Augustine can be represented as (4x + 5) miles. The distance from Pensacola to St. Augustine is 395 miles. Is Tallahassee the midpoint of Pensacola and St. Augustine? Show your work to support your conclusion.
7x+45=395
7x=350 so x=50
NOW see if
3 x + 40
is half of 395
3x+40 = 150 + 40 = 190
twice 190 = 380
SO NO
