answer: $11.40
explanation: turn the percent into a decimal, multiply it by the starting cost, then subtract the product from the starting cost 
>> 40% = 0.40 
0.40 x 19 = 7.60
19 - 7.60 = 11.40
 
        
                    
             
        
        
        
Answer:
a
Step-by-step explanation:
solve for y in one equation
2x + y = -4
y = -4 - 2x
plug y into the other equation
5x + 3y = -6
5x + 3(-4 - 2x) = -6
5x -12 -6x = -6
-x - 12 = -6
-x = 6
x = -6
plug x into the equation to find y
y = -4 - 2x
y = -4 - 2(-6)
y = 8
ordered pair: (-6,8) 
 
        
             
        
        
        
Well it has to be either 23 or 9 because you have to add the two smallest sides also you have to subtract them . What are the options ?
