Answer:
Mechanic 1: $55 per hour
Mechanic 2: $105 per hour
Step-by-step explanation:
Given
Represent the rate of the first mechanic with x and the second with y.
So, we have:

The total earnings is: $1850, so we have:

Required
Determine the rate of each
The equations are:
--- (1)
--- (2)
Divide (2) through by 5
--- (3)
Subtract (1) from (3)


Divide through by 2


Substitute 105 for y in (1)

Make x the subject

Substitute 105 for y


Hence:
Mechanic 1: $55 per hour
Mechanic 2: $105 per hour

<em>Question:</em>
<em>Abraham has visited at least 50 countries; he plans to visit five new countries per year (Y) for the next several years. Which inequality and solution shows the amount of years they will take for Abraham to meet his goal.</em>
Answer:


Step-by-step explanation:
Given
------ at least

Required
Represent as an inequality
"at least" means 
So the countries he has visited can be represented as thus;

If
1 year = 5 countries
y years would be 5y countries
So, in y years; he'd have visited

To determine the value of y.
We have that
<em>in the world</em>
<em>Substitute 195 for Countries</em>

<em>Collect Like Terms</em>


<em>Divide through by 5</em>


<em>Reorder</em>

This means that; he'll visit all countries in at most 29 years' time
