Problem 2

Midpoint: Think 1/2. A midpoint cuts a line segment in 1/2 (in this question). That means that the left segment = the right segment. Remember: midpoint means 1/2.

LN is given as 14.

LM is 1/2 the distance of 14

LM = 1/2 * 14

LM = 7

Problem 3

If the midpoint = the 1/2 way point, the two halves are equal. Remember a midpoint divides the 2 parts into 2 EQUAL parts.

4a - 2 = 18          Add 2 to both sides

4a = 18 + 2

4a = 20

a = 20 /4

a = 5

Problem 4

Remember that midpoint means 1/2. That a midpoint cuts a segment into 2 equal segments

Equation

2n + 2 =  5n - 4      

Solve

2n + 2 = 5n - 4      Add 4 to both sides

2n + 2 + 4 = 5n     Subtract 2n from both sides.

6 = 5n - 2n

6 = 3n                    Divide both sides by 3

6/3 = n

n = 2

<u>Answer:</u> B

Problem 5

And again the whole line segment is divided into 2 equal parts.

<u>Equation</u>

6p - 12 = 4p           Add 12 to both sides

6p = 12 + 4p           Subtract 4p from both sides.

6p - 4p = 12

2p = 12                   Divide by 2

p = 12/2

p = 6           <<<<< Answer
