Take away $13.50 dollars since he needed that to get in the fair.
He had $22.5 left that he spent.
And there are 9 tickets that he bought.
22.5 divided by 9 is 2.5.
Therefore, each ticket cost $2.5.
I hope this helps, good luck.
Answer:
X^2+5x-50
Step-by-step explanation:
X^2-5x+10x-50
The direct variation of the time it takes to fill the tank with the volume of the tank may be presented by the following equation,
V = kt
where V is volume, t is time and k is the constant of direct variation.
To solve for k, substitute the known data in the equation above,
400 gal = k(1 hour) ; k = 400 gal/ h
For the second condition,
600 gal = (400 gal/h) t ; t = 1.5 hours
Therefore, it will take 1.5 hours to fill a 600-L tank.
3x - y = 5 Equation l
x - y = 1 Equation ll
By elimination
-Multiply equation l by -1
-3x + y = -5
x - y = 1
-2x = -4
Solve for x
x = -4/-2
x = 2
-Find y
2 - y = 1
-y = 1 - 2
-y = -1
y = -1/-1
y = 1
Solurtion: x = 2, y = 1
