Answer:
First mechanic worked 20 hours and second mechanic worked 5 hours
Step-by-step explanation:
Let the number of hours the first mechanic worked = 
Let the number of hours the second mechanic worked = 
Therefore, we can write 2 equations and then solve them simultaneously:
Rearranging the first equation: 
and substituting into the second equation to find :
Now sub 
into the first equation to find
Therefore, first mechanic (a) worked 20 hours and second mechanic (b) worked 5 hours

(B) –9 < x – 4 < 9 inequality is equivalent to Ix-4I <9.
<h3>
What is inequality?</h3>
- Inequality is a statement of an order relationship between two numbers or algebraic expressions (greater than, greater than, or equal to, less than, or less than or equal to).
- Inequality is defined as a difference in size, amount, quality, social position, or another factor.
- Inequality occurs when you have ten of something and someone else has none.
- (mathematics) A statement stating that one quantity is less than (greater than) another.
So, Ix-4I <9:
- |x-4|<9 ⇒ -9 < x-4 < 9
- -5 < x < 13
Therefore, (B) –9 < x – 4 < 9 inequality is equivalent.
