Okay uh

x = 2y + 9
14x + 2y = - 54

14x + 2y = - 54
14(2y + 9) + 2y = - 54
28y + 126 + 2y = -54
30y + 126 = -54
- 126 -126
30y = -180
30y/30 = -180/30
y = -6

x = 2y + 9
x = 2(-6) + 9
x = -12 + 9
x = -3

(x, y) = (-3, -6)

A car was sold at $34000. That price was 85℅ of the orginal price. What was the original price?
Art [367]
Hey there! The answer is $40000

<span>A car was sold at $34000. That price was 85℅ of the orginal price.
When we know 85% of the original price we can find 1% of this price by dividing by 85.

1% of the original price = $34000 / 85 = $400
</span>When we know 1% of the original price we can find 100% of this price by multiplying by 100.

100% of the original price = original price = $400 * 100 = $40000
The answer is $40000

Please help it OVER DUE
kotykmax [81]

You know the total amount, 32.00, and the cost of each gallon, 1.60, so you can make an equation using x as the amount of gallons bought.

1.60x = 32.00

Now just divide 32.00 by 1.60

x= 32.00/1.60

x= 20
