Add 5 on both sides:
Divide both sides by -10 and reverse the inequality:
The number line is shown in figure attached.
Option A is correct.
Option B is incorrect because x cannot be less than -3
Option C is correct because −3 less than or equal to x is -3 ≤ can be written as: x≥-3
Option D is correct because when x is greater than or equal to the circle is closed and greater values are on right side of the number line.
So, Option B is correct.

The first number in terms of x:
The second number in terms of x:
If we add them all up, these 3 numbers in terms of x must be equal to 104, so:
Now that we know the second number, we can find the other numbers since we already figured out their values in terms of x:
The first number is 9, second number 19 and the third number 76.
