The solution set of the inequality 9x ≥ 117 is [9, ∞).
What are inequalities and their types?
Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, An inequality 9x ≥117.
Dividing both sides by 9 we have,
(9/9)x ≥ 117/9.
x ≥ 13.
Therefore, The solution set of the inequality is [9, ∞).

3y + 2/4 = 7
You could multiply each side by 4 to get rid of the fraction:
12y + 2 = 28
Subtract 2 from each side:
12y = 26
Divide each side by 12 :
y = 26/12 or 13/6 or 2 and 1/6

Answer:
The value of x is 7
Step-by-step explanation:
Here, angle x + 16 and Angle 4x - 5 are two vertical angles given,
Now,
x + 16 = 4x - 5
4x - 5 = x + 16
4x - x = 16 + 5
3x = 21
x = 21 ÷ 3
x=7
Thus,The value of x is 7

The value of x when the angles are vertically opposite is 7
Given,
Angle x + 16 and Angle 4x - 5 are vertically opposite angles .
Here, angle x + 16 and Angle 4x - 5 are two vertical angles given,
Now,
x + 16 = 4x - 5 (Vertically opposite angles are equal.)
4x - 5 = x + 16
4x - x = 16 + 5
3x = 21
x = 21 ÷ 3
x = 7
Thus, The value of x is 7

In 6 hrs, the welder who does 1/15 of the job in 1 hr and the welder who does 1/x in 1 hr, complete the job (6 hrs.)
Multiply 30 on both sides to cancel out the fractions and we get:
Solving for x:
30/x=3
3x=30
x=10
The second welder would take 10 hours.
