Aused appliance store estimates that the value of an oven-range combination decreases by about 10% in the first year of use. if the original price of a one-year-old oven-range combination was $1,100, what is the value of the oven-range now?

Assuming that NOW represents 1 year of use, then the value of the oven-range is (1 - 0.10)($1100), or 0.90($1100), or $990.

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

The answer is 1 because you have to flip the sign when dividing by negative number and 3
