Question Solve 9 < 3x + 6< = 15 and write the solution in interval notation. If there is no solution, type Ø.

Given:

The compound inequality is

To find:

The solution for the given compound inequality in interval notation.

Solution:

We have,

Subtracting 6 from each side, we get

Divide each side by 3.

Here, 1 is not included in the solution set and 3 is included in the solution set.

Therefore, the solution in interval notation is (1,3].

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

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
