The correct answer is: [C]: " 40 cm " . _________________________________________________________ Explanation: _________________________________________________________
Divide each side of the equation by "5" ; to isolate "x" on one side of the equation; & to solve for "x" ; ________________________________________________________ 5x / 5 = 200 / 5 ;
x = 40 . ________________________________________________________ The correct answer is:[C]: " 40 cm " . ________________________________________________________
You have the actual length, 200 ft, and you have to find the model length, x. the ratio is 5:1. you put length over ratio. it becomes 200/5 = x/1. x/1= x. 200/5= x. then do 200/5, which is 40. x, or the length of the model, is 40 ft. hope i helped.
