c
Step-by-step explanation:
Using Pascal's triangle, the expansion, although EXTREMELY lengthy, will help you find the 7th term. I am going to type out the expansion only up til the 7th term (although there are actually 10 terms because we are raised to the power of 9). If you would like to learn how to use Pascal's Triangle for binomial expansion, you will need to visit a good website that explains it because it's just too difficult to do it via this website.
The expasion is as follows (up to the 7th term):
That last term is the 7th term. You find out its value by multiplying all the numbers together and adding on the c^3d^6. Again those come from Pascal's triangle, and it's one of the coolest math things ever. I encourage you to take the time to explore how it works.
Answer:
a) System of equations will be:
b) Number of adult tickets sold = 263
Number of students tickets sold = 237
Step-by-step explanation:
Let:
Number of adult tickets sold = x
Number of students tickets sold = y
a)
As Marc sold total 500 tickets, the expression will be:
Student tickets cost $2 and adult tickets cost $5. Marc's sales totalled $1,789.
The expression will be:
So, system of equations will be:
b)
Solve the system to find value of x and y
Let:
Multiply equation 1 by 2 and subtract
We get value of x = 263
Now finding value of y by putting value of x in eq(1)
We get value of y = 237
Number of adult tickets sold = x = 263
Number of students tickets sold = y = 237
