Aduct must be 8 feet 9 1/2 inches long. it is assembled from pieces that are 1 foot 11 1/2 inches long when assembled. how many pieces are required and how much waste must be cut off the long section?

8 feet x 12 = 96 +9 1/2 = 105 1/2 inches

1 x 12 = 12 + 11 1/2 = 23 1/2

105 1/2 / 23 1/2 =4.489

 they will need 5 pieces, they will have 12 inches left over

there is no

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
