Hey there! Welcome to Brainly.
Let's solve using order of operations (PEMDAS), which is Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
First, we solve the parentheses.
9+6÷6
Now we take care of the division.
9+1
We add.
10
Therefore, your answer is 10
I hope this helps!
Answer:
150 student tickets and 375 adult tickets
Step-by-step explanation:
Let x = # of student tickets sold, and y = # of adult tickets sold.
Total of 525 tickets were sold, so the first equation is x + y = 525. The register gained $8325, so 10.50x + 18y = 8235 is the second equation.
x + y = 525
10.50x + 18y = 8325
18x + 18y = 9450
10.50x + 18y = 8325
7.5x = 1125
x = 150
150 + y = 525
y = 375
The number of permutations is 5!.
5! = 5 x 4 x 3 x 2 x 1 = 120
