5 0
Ok so:
90 + 6x - 7.5x < 30

6x - 7.5x = -1.5

90 - 1.5x < 30
-90           -90
-1.5x   < -60

-60/-1.5

x=40

40 < 30

F the point T is between the points B and N, then which of the following is true?
valentina_108 [34]
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.
