points a,b,c,and d lie on a straight line in the given order. AC = 25 cm and BD = 46 cm. The ratio of length CD to AB is 5/2. Find the length of line segment BC in cm.

sorry miss the CD part

ahh, that's better

make a sketch of a line and label point A, B, C, and D

using CD : AB = 5:2

label AB = 2x and CD = 5x , giving you the 5:2 ratio

From AC = 25 you can now label BC as 25-2x

From BD = 46 you can label BC as 46-5x

so obviously 25-2x = 46-5x

x = 7

sub back in either of BC expressions, to get BC = 11
