Ryan is building a tree house. it will take 85 1/4 hours to complete. he can work on the tree house 15 1/2 hours each week. to the nearest tenth, how many weeks will it take ryan to complete the tree house

5 1/2 weeks. you divide 85 1/4 by 15 1/2 to get the answer

5.5 weeks

Step-by-step explanation:

85.25 / 15.5

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
