How do I solve this equation?

- 1 ≤ x ≤

Step-by-step explanation:

Inequalities of the type | x | ≤ a , always have solutions of the form

- a ≤ x ≤ a

Given

| 4x - 3 | ≤ 7 , then

- 7 ≤ 4x - 3 ≤ 7 ( add 3 to the 3 intervals )

- 4 ≤ 4x ≤ 10 ( divide each interval by 4 )

- 1 ≤ x ≤ , that is

- 1 ≤ x ≤

Range = 19 .

Step-by-step explanation:

Given  : 19, 12, 13, 3, 0, 0, 0, 0, 0, 0, 2, 13 .

To find : What is the range of the data values.

Solution : We have given

Data :  19, 12, 13, 3, 0, 0, 0, 0, 0, 0, 2, 13 .

Range :  highest value  -  least value .

Highest value = 19 .

Least values  = 0.

Range = 19 - 0 .

Range = 19 .

Therefore, Range = 19 .
