Answer:
Step-by-step explanation:
This is a parallelogram. In parallelogram, opposite sides are equal.
x + 3 = 6
      x = 6 - 3
      x = 3
 
        
                    
             
        
        
        
I don’t quite understand this question since it’s all spaced out and there’s no picture but since domain is x/the indecent variable, “x = -6, -1, 0, 3” (the first answer choice” is correct
        
             
        
        
        
Answer:
$1.12
Step-by-step explanation:
One way to solve this problem is through an algebraic equation. Set up the equation like this,  . This equation works because 3.28 is subtracted from 10, which represents how much was spent in total. Then, this is equal to 6x, which represents the total cost of six keys.
. This equation works because 3.28 is subtracted from 10, which represents how much was spent in total. Then, this is equal to 6x, which represents the total cost of six keys.
So, to solve first subtract 3.28 from 10, this gives you 6.72. Then, divide both sides by 6. This equals 1.12, which is the cost of each key.
 
        
                    
             
        
        
        
Smaller leg = x
longer leg = y
hypotenuse = z
y=x+7
z=x+8
due to 

but x cannot be -3 
so smaller leg is 5 inches
then longer leg = 5+7 = 12 inches
and hypotenuse = 5+8 = 13 inches
 
        
        
        
If it's relationship Akira : Business A. = 7:5 
The part of Akira is 7k
and the part of the Business A. is 5k 
Then
7k+5k=12k => 12k=1,800,000 => k= 1,800,00/12=150,000$
Akira part is 7k= 7 * 150,000 = 1,050,000$
Good luck!!!!
