Answer:

d) 10

solve:

1) divide 10 by \frac{1}{2}

⇒ 10 ÷ \frac{1}{2}  = 5

2) add 8 to 5

⇒ 8 + 5 = 13

M is between L and N. If LN = 91 and LM = 23, find MN.
Tasya [4]

Answer:

MN = 68

Step-by-step explanation:

LN = 91

LM = 23

Points L, M, and N are collinear, therefore, according to the segment addition postulate, the following can be deduced:

LM + MN = LN

23 + MN = 91 (Substitution)

Subtract 23 from both sides

23 + MN - 23 = 91 - 23

MN = 68
