I hope this is right, the negatives should go first because you are taking away, then positives 
        
             
        
        
        
Let x and y be the rate per hour for Mechanic 1 and 2 respectively.
Then,
x+y=205 ---------- (1)
Additionally,
10x+15y = 2500 ------ (2)
Solving equations 1 and 2;
Multiply (1) by 10 and subtract two from the result,
10x+10y = 2050
10x +15 y =2500
----------------------
        -5 y = --450 => y = 450/5 = $90
Then,
x= 205-90 = $115
Therefore,
Mechanic 1 charged $115 per hour
Mechanic 2 charged $90 per hour

Answer:
- sin(X) = 4/5
- cos(X) = 3/5
- tan(X) = 4/3
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to help you remember the relations between sides and trig functions in a right triangle.
   Sin(X) = Opposite/Hypotenuse = 24/30 = 4/5
   Cos(X) = Adjacent/Hypotenuse = 18/30 = 3/5
   Tan(X) = Opposite/Adjacent = 24/18 = 4/3
