<u>Answer:</u>
$50 and $115
<u>Step-by-step explanation:</u>
We know that,
the sum of the two rates = $165 per hour
Let x and (165 - x) represent the $/hour of the 15hr and 5hr mechanics respectively.
Then combining their charges together to get:

Solving for x to get:



So the rate charged per hour by one mechanic is $50 and for the other mechanic =
$115.
Answer:
look on go ogle or you tube I think there's something on there
4=x/3-5
4=x/-2
x=-8
so -8 it is
The answer will be 10 as the ratio is 4. 10 x 4 = 40
