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
A college student is looking at her monthly checking account records. On September 1, 2008, her checking account held a balance of $1,050.

Answer:
C. 128ft
Step-by-step explanation:
it's C because whenever it says and you're supposed to multiply always remember that :) = (which means area ofc) you're finding the so you multiply 16x8 and the you get your answer (: ignore the 640 you just focus on the 16 and 8 ok? 16x8=128! :))
