A) Tonya bought 3 games at X price, so 3X would be total amount.
B) Tony's cost was 0.50 less than X, so x-0.50, he bought 4 games, so he spent 4(x-0.50).
C) Set those to equal to solve for x:
3x = 4(x-0.50)
D) Solve:
3x = 4(x-0.50)
Distribute:
3x = 4x - 2
Subtract 4x from both sides:
-X = -2
Multiply both sides by -1:
X = 2
E) Since X is the amount Tonya paid per game, Tony paid X - 0.50, so Tony paid 2 - 0.50 = $1.50 per game.
Check:
Tonya: 3x = 3(2) = $6 total
Tony: 4(x-0.50) = 4(2.00 - 0.50) = 4(1.50) = $6 total

Step-by-step explanation:
The ordered pairs that are a solution to the equation y=4-2x are (0,4) and (-1,6)
Answer:
1 1/3 minutes
Step-by-step explanation:
Gasoline is pumped at rate of 3 gallons per minute into a container that already has 4 gallons inside
From the above question, we are to calculate the time at which the gasoline is pumped into the container
Hence:
Time = Number of gallons/Rate
Number of gallons = 4
Rate = 3 gallons per minutes
Hence:
Time = 4 gallons/3 gallon per minutes
Time = 1 1/3 minutes
The time at which the gasoline is pumped into the container is 1 1/3 minutes
Using systems of equations, you can find the number of tickets by elimination.
S are students and A are adults.
S+A=8
7.25A+5.50S=52.75
Multiply the first equation by -5.50 to eliminate S.
-5.50A-5.50S=-44
7.25A+5.50S=52.75
1.75A=8.75
8.75÷1.75=5
There were 5 adult tickets and 3 students.
