Answer:
 C= 7.6761229314
Step-by-step explanation:
 the formula is c=d/p 
d= 324.7 
p= 42.3
so ... this is how to calculate...
C = 324.7 km/ 42.3 litres 
I hope it can help. thanks
 
        
             
        
        
        
Answer:
The answer to your question is:
 x = -10; y = 8
Step-by-step explanation:
Solve equations by elimination method                          
                                               2x + 3y = 4    (1)
                                                x + 2y = 6    (2)
Multiply 2 by -2
                                               2x + 3y = 4
                                              -2x - 4y = -12
                                                     -y = -8
                                                      y = 8
Substitute y in (2)
                                              x + 2(8) = 6
                                             x = 6 - 16
                                             x = -10
 
        
             
        
        
        
The surface area of the right triangular prism is 270 sq ft
<h3>Total surface ara of the prism</h3>
The total surface area of the prism is the  sum of all the area of its faces
For the two triangles
A = 2(0.5bh)
A = bh
A = 7 * 12 = 84 sq.ft
For the two rectangles
A = 2lw
A = 2(6*12)
A = 2 * 72 = 144 sq.ft
For the third triangle;
Area  6ft * 7ft
Area = 42 sq.feet
Taking the sum of the areas
TSA = 84 + 144 + 42
TSA  = 270 sq ft
Hence the surface area of the right triangular prism is 270 sq ft
