The given equations are:
5x - 2y = 88
3x + 4y =  58
Multiplying the 1st equation by 2, we get the new set of equations as:
10x - 4y = 176
3x + 4y = 58
Adding the two equations, we get:
10x - 4y + 3x + 4y = 176 + 58
13x =234
x =  18
Using the value of x in 1st equation, we get:
5(18) - 2y = 88
- 2y = 88 -5(18)
-2y = -2
y = 1
So, the solution of the equation is (18, 1)
        
                    
             
        
        
        
I assume that you mean 3 times 5 feet means how many feet and inches
so the answer is 5 feet and <u>blank </u> inches
or 12 inch in 1 feet so 12 times 5=60 so 60 inches
or you may have forgotton to put a number before the first inch word like 5 feet <u>3</u> inch
        
             
        
        
        
To solve this problem you must apply the proccedure shown below:
 1. You must apply the Law of Cosines, as you can see in the figure attached. Then:
 - The first ship travels at  in for two hours. Therefore, the side
 in for two hours. Therefore, the side  is:
 is:
 
 - The second ship travels at  for
 for  . Therefore, the side
. Therefore, the side  is:
 is:
 
 - Now, you can calculate  :
:
 
 The answer is:
