Which describes how to calculate the range of this data set?

4, 5, 6, 8, 11, 12
Subtract 11 - 5
Subtract 12 - 4
Add 11 + 5
Add 12 + 4

12 - 4

Step-by-step explanation:

To get the range, subtract the lowest number from the highest

The highest number is 12

The lowest number is 4

Range = 12 - 4

= 8

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
