Apiano keyboard is 4 feet long. is a line of 3 keyboards longer than 3 yards?

Yes. It's longer than 3 keyboards because 3 ft=1 yard so that means 12/3 would be 4 yards. And 4 yards is longer than 3 yards. I hope this helped ^^

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

6(2x + 5y)6 (2x) = 12x6 (5y) = 30y12x + 30y
