Answer:
3/11
3:11
Step-by-step explanation:
 
        
                    
             
        
        
        
k = 18
the common difference d of an arithmetic sequence is
d = a₂ - a₁ = a₃ - a₂ = ....
a₂ - a₁ = 2k - 1 - k - 9 = k - 10 and
a₃ - a₂ = 2k + 7 - (2k - 1) = 2k + 7 - 2k + 1 = 8, hence
k - 10 = 8 ⇒ k = 8 + 10 = 18
the 3 consecutive terms are
27, 35, 43 
 
        
             
        
        
        
  1x+ 3y = -12x + 2y = 6
+12x         +12x
  13x + 3y = 2y = 6 
           +3y  +3y
  13x = 5y = 6 
13x = 5y and 5y = 6 
        
             
        
        
        
The value of x in the diagram is 8 feet that makes the combined area of the house and the porch to be 733 ft²
<h3>How to calculate 
area?</h3>
 Combined area = big rectangle + smaller rectangle - triangle
Hence:
733 = (13 * (59 - x)) + (x * 9) - 0.5(9 - 7) * (x - 6)
733 = 767 - 13x + 9x - x + 6
x = 8 feet
The value of x in the diagram is 8 feet that makes the combined area of the house and the porch to be 733 ft²
