Question

f the point T is between the points B and N, then which of the following is true?
A. BT+BN=TN
B. NT+BN=BT
C. BN-TN=BT
D. TN-BN=BT

Answer 1

Assuming T, B and N are all on the same line, then we can say

BT + TN = BN

which is the segment addition postulate. 

Subtract TN from both sides to get
BT + TN = BN
BT + TN - TN = BN - TN
BT = BN - TN
BN - TN = BT

Which is what choice C is saying. Therefore the answer is choice C.
