Ok so do 5x12=60
then do 2x3=6
after do 1/2(3x4)=6
then do 60-12=48
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.
(This method used in math is technically called "Solving Systems of Equations", just fyi).
15 is just 10% of a number. 10% is 1/10 of a hundred percent, so to find the 100%, multiply 15 by 10 and get: 150
Answer:
I haven't done expressions in a while but I say the safest bet would be D.
The answer would be the 3rd one, we find this by gettign our facts, first find our y-intercept, where does the line pass through the y line, it passes through the positive 4, now lets find the slope, the slpe is the rise over run, the graph rises 4 and runs 1 to the right, so your slope will be 4 now how do you know if its a positive or a negative, well if the graph rises to the right it is a positive and if it rises to the left is a negative... This graph rises to the right so our slope is a positive... SO our equations should look like f(x)=4x+4 and our 3rd option has exactly this answer, so your answer would be the 3rd one
Hope this helps
