Best ResponseYou've already chosen the best response.0The way you begin is to decide which section gets x. In the first sentence you see the length of the second section is..... and the length of the third section is..... YOU NEVER SEE the length of the first section is.... so that is the section that gets the "x"

Best ResponseYou've already chosen the best response.0first section = x second section = x + 1 (one foot more than the first section) third section = 3x  1 ( one foot less than three times the first section)

Best ResponseYou've already chosen the best response.0If you add the three sections together you get the entire rope which is 30 ft.

Best ResponseYou've already chosen the best response.0So x + x + 1 + 3x  1 = 30

Best ResponseYou've already chosen the best response.0Add like terms. 5x = 30 (x + x + 3x = 5x and 1  1 = 0)

Best ResponseYou've already chosen the best response.0first section = x which is 6ft second section = x + 1 which is 6 + 1 = 7 ft. third section = 3x  1 which is 3(6)  1 = 18  1 = 17 ft. 6 + 7 + 17 = 30 ft.
