<h3>Given</h3>
- C is midpoint of AB
- B is between A and D
- AD = 15
- BD = 7
- Find CD
<h3>Solution</h3>
- CD = CB + BD = 
- 1/2AB + BD = 
- 1/2(AD - BD) + BD =
- 1/2(15 - 7) + 7 =
- 1/2(8) + 7 =
- 4 + 7 =
- 11

Answer:
A, B, & C
Step-by-step explanation:
A: -5x +12 = -12x - 12
     +12x        +12x
     7x + 12 = -12
          -12     -12
             7x = -24                 [Divide both sides by 7 to get x]
               x = -24/7
B: −5x + 12 = 5x + 12
    -5x            -5x
     -10x + 12 = 12
             -12     -12
             -10x = 0                   [Divide both sides by -10 to get x]
                  x = 0
C: −5x + 12 = 5x − 5
     -5x           -5x
     -10x + 12 = -5
             -12      -12
            -10x = -17                  [Divide both sides by -10 to get x]
                x = 17 / 10
D: −5x + 12 = −5x − 12
     +5x           +5x
               12 ≠ -12         [The statement is false, so it isn't the correct answer]
