Step-by-step explanation:
You just had to make common denominators and then your would subtract
 
        
                    
             
        
        
        
Step-by-step explanation:
-7/2 = -28
-7 = -28 × 2
-7 = -56
 
        
             
        
        
        
2.5 because if you move x to the other side of the equation you will get y=2.5x, and the constant of proportionality is what x is multiplied by, in this case, it's 2.5.
        
             
        
        
        
The circle: x = 4 y = 0.5
The square: x = 3.5 y = 1.5
The triangle: x = 0 y = 2.5
        
             
        
        
        
Ist amount paid = $1500
Making $350 for 10 months = 10*350 = $3500
Total amount paid  = 1500 + 3500 = 5000
So an amount of $5000 was paid to cover the cost of $4500 within the ten month period.
I = PRT
Interest, I = 5000 - 4500 = 500Time, t = 10 months = 10/12 = (5/6) year.Principal P = 4500
R = I /(PT)  R = 500 / (4500*5/6)
R = (500*6) / (4500*5)
R = 0.1333..
R ≈ 13.33 %  per annum.
