Alright, lets get started.
Suppose first mechanic charges= x
So, second mechanic charges will be = 
(because total of their rates was 125)
first mechanic worked for 5 hours, and the second mechanic worked for 15 hours and together they charged a total of $1225
Means
Adding 10 x in both sides
Subtracting 1225 from both sides
Dividing 10 in both sides
x = 65
For second mecahnics rate = 125 - 65 = 60
Hence The mechanic who worked 5 hours charged $ 65 per hour, the one who worked 15 hours charged $ 60 per hour: Answer
Hope it will help :)
1) 5x - 6y = -32 --> equation 1
3x + 6y = 48 --> equation 2
eliminating y from both of the equations and adding the rest of the terms
we get,
8x = 16
dividing 8 on both sides
x = 2
Substituting the value of x in equation 1
5(2) - 6y = -32
10 - 6y = -32
-6y = -12 ( dividing both sides by -6)
y = 2
2) -3x - 3y = 9 ---> equation 1
3x - 4y = 5 --> equation 2
eliminating x from both equations and adding the rest of the terms
we get,
-7y = 14 ( dividing both sides by -7 )
y = -2
Substituting the value of y in the equation 1
-3x - 3(-2) =9
-3x + 6 = 9 (subtracting both sides by -6)
-3x = 3
x = -1
Hope this helps you.. :)
Answer:

Step-by-step explanation:
Answer:
The value of the stolen merchandise is 31.43
Step-by-step explanation:
Given as :
The number of cases of beer stolen = 7
Number of packs in each cases = 6
And The price of each six pack is 4.49
So, As the price of each six pack is 4.49 and number of pack in each case is 6
And the number o stolen cases is 7
So, The value of total stolen item = 7 × 4.49 = 31.43
Hence The value of the stolen merchandise is 31.43 Answer
