To fit in an existing frame, the length, x, of a piece of glass must be longer than 12 cm but not longer than 12.2 cm. which inequality can be used to represent the lengths of the glass that will fit in the frame

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

Write an inequality and solve each problem.for exercises 11 and 12, interpret the solution.
