Rewrite the equations i slope intercept form (they are in standard form)1- 6x+24y = 182- 8x+14y = 23- 6x+y = 14- -4x-2y = 165- 2x+3y = 116- -9x+4y = 57- 2x+y = 68- 2x+3y = 39- 3x+2y = 10select the equation that has a unit rate of 3/4. mark all that applya) 3x-4y = 0b) 4x+y = 0c) 9x-12y = 0d) 12x+9y = 0e) 15x-20y = 0f) -8x+6y = 0

2. is a and c. sorry I couldn't help more

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
