Mazzeo's Appliance Store requires a down payment of on all install-
Tomtit [17]

Answer:

Norton's

Step-by-step explanation:

Suppose that the down payment of Mazzeo's store = 1/3 on all installment purchases

Whereas Norton's depot required 30% down payment on installment purchases.

1/3 is fractional value of 33.33%.

therefore, Norton's Store's down payment rate is lower than that of Mazzeo's store.

4 (2x-6)=10x-6. solve for x
Reika [66]

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 

   4*(2*x-6)-(10*x-6)=0 


   2x - 6  =   2 • (x - 3) 

   8 • (x - 3) - (10x - 6) = 0 

   -2x - 18  =   -2 • (x + 9) 

 -2 • (x + 9) = 0 

Solve :    -2   =  0

<span>This equation has no solution.
</span>A a non-zero constant never equals zero.

Solving a Single Variable Equation : 
 Solve  :    x+9 = 0 

<span>
 </span>Subtract  9  from both sides of the equation :<span> 
 </span>                     x = -9

+15 + 15

8x = 64
