Answer: X=1/4 or X=0.25
Step-by-step explanation:
-3+12x
Bring the 3 to the other side to isolate x
12x=3
Divide both sides by 12
x=0.25
Their are 40 different ways the students could sit
The answer is 110 adult tickets. Let x= student tickets and y= adult tickets.
We know that the total tickets sold was 440. That means the total number of student tickets (x) plus the total number of adult tickets (y) equaled 440. Putting it into an equation, you get:
x+y=440
Now we know that the amount of student tickets is equal to three times as many adult tickets, so in an equation that is seen as:
x=3y
In order to solve for one variable, plug in 3y for the x value of the first equation to get:
y+3y=440
then solve:
4y=440
y= 440/4
y=110
The total number of adult tickets sold was 110 tickets.
