M is the
midpoint of CD. Given
-------------------------------------------------
Both ends of the
line segment to
M is equal. Definition of midpoint
-------------------------------------------------
CM = 5x-2 and
MD = 3x+2. Given
-------------------------------------------------
CM = MD. As above, definition
of midpoint
-------------------------------------------------
5x-2 = 3x+2. Substitution
-------------------------------------------------
5x-3x = 2+2
2x = 4 Rules of Algebra

Answer:
Therefore, we conclute that the map distance between A and C is 35 m.u..
Step-by-step explanation:
We know that the order of three loci is A B C, and the map distance between A and B is 15 m.u., and the map distance between B and C is 20 m.u. We calculate the map distance between A and C.
Therefore, we get
Therefore, we conclute that the map distance between A and C is 35 m.u..
-14 1/9 - 2 9/10
Convert the mixed numbers into improper fractions
-127/9 - 29/10
Multiply until both fractions have the same common denominator
-1270/90 - 261/90
Subtract the numerators but NOT the denominators
Final Answer: -1531/90 or -170 1/9 *Both fractions are equivalent to each other.
Equation: 3x = (5x-30)
Solve:
3x-5x=-30
-2x=-30
Divide each side by two
x=15
