mezya [45]

Answer:

The price of the tv before tax is 410

Step-by-step explanation:

Let x = price of tv before tax

tax = x*  9%

tax = .09x

The total cost is price of tv before tax plus tax

total cost = x + .09x

total cost = 1.09x

446.90 = 1.09x

Divide each side by 1.09

446.90/1.09 = 1.09x/1.09

410 = x

The price of the tv before tax is 410

7.) Nate has $267 in bills. None of the bills is greater than $10. He has eleven $10 bills. He has seven fewer $5 bills than $1
slavikrds [6]
Just set up 2 equations. 

267 = 10(11) + 5(x) + 1(y) 
x = y - 7 

you can plug the second into the first and get 

267 = 110 + 5(y - 7) + y 
157 = 5y - 35 + y 
6y = 192 
y = 32 
x = 32 - 7 = 25 

thus, 32 $1's and 25 $5's
