(08.02)the ages of several trees on school property are shown below: 3 years, 8 years, 10 years, 14 years, 11 years what is the mean age of these trees?

The average age is 9.2 years

Step-by-step explanation:

Add up:

 3 years

 8 years

10 years

14 years

+ 11 years

 46 years

Now divide this sum by the number of trees (5), to obtain the average (mean) age:  46 years / 5.  The average age is 9.2 years.

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
