Solve and graph the inequality 6.7> -0.2x+4.5 look at picture to get the exact equation and answer choices!

Let's do it !

(6.7 ≥ -0.2x + 4.5)
↔ (6.7 - 4.5 ≥ -0.2x)
↔ (2.2 ≥ -0.2x)
↔ (2.2/-0.2 ≤ x)
↔ (-11 ≤ x)

In short, the answer would be : D. x ≥ -11.

Hope this helps !

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
