$26.46 
I divided 15.12 by 8 to get the cost of just one gallon , which was $1.89. 14 x 1.89 = 26.46, which would ideally be the cost to fill a 14-gallon tank.
        
             
        
        
        
Hey!
Hope this helps...

Assuming that the sum of all the angles must equal 180°
180 - (27+10) = k
180 - 37 = k
k = 143°
 
        
             
        
        
        
Answer:
x = -4/11
Step-by-step explanation:
add the x values. 
11x+8=4
subtract 8 from each sides 
11x=-4 
divide by 11
x=-4/11
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Firat triangle has a=4cm and b=a and P1=a*b/2=4*4/2=8cm^2
First parallelogram has h=4cm (from first triangle) and a=5.7cm
P2=a*h=22.8cm^2
Big triangle has h=4 and a=5.7+4=9.7
P3=a*h/2=9.7*4/2=19.4
And 4th triangle has the same are lik the first one, P4=8.
P=8+22.8+19.4+8=58.2cm^2
 
        
             
        
        
        
The  difference between 1/8 and 6/10 = 0.475 , does this help?
