Answer:
The system is of equations is: 

Where g is the amount of general tickets and r is the amount of reserve tickets. 
35 general tickets and 25 reserve tickets were sold. 
Step-by-step explanation:
Let general tickets be represented by g and reserved tickets be represented by r. 
Each general ticket sells for $10 each and reserved tickets $15 each. Dave collected a total of $725. Thus: 

And a total of 60 tickets were sold. Hence: 

Our system of equations is: 

We can solve by substitution. First, divide both sides of the first equation by 5: 

Next, we can subtract a variable (r in this case) from the second equation: 

Substitute: 

Distribute: 

Simplify:

Subtract: 

Using the previous equation: 

Substitute and evaluate: 

So, 35 general tickets and 25 reserve tickets were sold. 
 
        
             
        
        
        
Answer:
Associative Property of Addition
Step-by-step explanation:
Looking at the expression, you can see that the numbers have been grouped differently. Based on the Associative Property of Addition, the sum of the numbers is the same despite the different pairing.
 
        
             
        
        
        
Depending on the first term, the sequences

would work.
If the sequence began at 6, 

If the sequence began at 1, 

If the sequence began at 3, 
 
 
        
        
        
Your answer is 8,000 minus 6 & 4

Answer:
Simplifying
f(r) = 5 + 1.75r
Multiply f * r
fr = 5 + 1.75r
Solving
fr = 5 + 1.75r
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'r'.
f = 5r-1 + 1.75
Simplifying
f = 5r-1 + 1.75
Reorder the terms:
f = 1.75 + 5r-1
