Alexis drove 1200 miles in 30 h. what was her rate of travel in miles per hour? *** me***

40 mph

First you have 1200/30. You are trying to get to 1 hour, so in order to get 30 to one, you must divide 30 by 30 and 1200 by thirty as well. You get 40 miles per hour.

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
