Frank needs to save $600 to buy a set of golf clubs. he plans to save $75 per month. write an equation that frank can solve to determine the amount of money he still has to save (y) in relation to the number of months (x) in which he has saved money.

X = number of months

y = amount needed to save

y = 600 - 75x

 y = 600 - 75x

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
