A rocket is divided into three sections. The top section is one sixth the length of the bottom section . The middle section is one half the length of the bottom section. The total length of the rocket is 180ft. Find the length of the top section.

18 feet long.

Step-by-step explanation:

Let the bottom section be x feet long, then:

x/6 + x/2 + x = 180

Multiply through by 6:

x + 3x + 6x = 1080

10x = 1080

x = 108 feet,

So the top section = 108/6

= 18 feet long.

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3
