(11/3-7/4)/[3.4-(1/2+2/3*3/2)]
First I converted fractions to mixed numbers.
11/3-7/4 / 3.4-3/2
Then, I solve the inside of the parentheses.
23/12 / 3.4-3/2

Hope this helps
The Four basic Mathematical Operations are:
•Addition
•Subtraction
•Multiplication
•Division
Y=3x plus or minus any number that is not 10.
The slope of your function has to stay 3x to be parallel with the function given. Just change the y-intercept (also known as the B value) to a number other than -10.
Answer:
x = 22
Step-by-step explanation:
I interpreted your problem as:

I simplified the problem to:

I combined like terms:

I moved all x to one side and all other constants to the other:

I divided by 3/2 (1.5) on both sides to isolate x:

Set x as adult tickets.
Set y as children's tickets.
x + y = 15
30x + 20y = 270
Solve for x in the first equation.
x + y = 15
x = 15 - y
Plug this into the second equation.
30x + 20y = 270
30(15 - y) + 20y = 270
450 - 30y + 20y = 270
450 - 10y = 270
-10y = -180
y = 18
If there is 18 childrens tickets, there should be -3 adult tickets.
This is impossible, and this impossible answer occured because the question is written wrong.
There are a total of 15 tickets
The smallest costing ticket is the childrens ticket, which costs 20$.
If he only bought children tickets, this would be 20x15 which is 300$.
300$ is over 270$, which makes the question impossible.
