Tony photocopied the image of a design for a monorail track system. The figure below shows the design and its photocopy.

The ratio of CD : BC is 2 : 3. The total length of track on the design is 58 meters. What is the length, in meters, of side GH on the photocopied image?

am i right?

anonymous · Answer

help mehhhhhhh :( please

anonymous · Answer

yes you are right :)

anonymous · Answer

x = 8
CD = 2x
so substitute
CD = 2(8)
CD = 16

anonymous · Answer

8 + 10 + 3x + 2x = 58

18 + 5x = 58 

5x = 58 - 18

5x = 40

5x/5 = 40/5

x = 8
