Answer:
Part A: a coefficient is either 20 or 35, both work. A variable is c or w, again either work.  The constant is 23.50.
Part B: He will have $503.50
Part C: The coefficient would change, because the amount per car changes, not the amount of cars.
Step-by-step explanation:
A coefficient goes in front of the variable (which is the letter, usually shown as x). The constant is a number with no variable attached. 
We replace c with 20, and w with 12, giving us 20(3)+35(12)+23.50 for our equation. After multiplying, we come up with 60+420+23.50, which equals 503.50.
 
        
             
        
        
        
Answer:
16
Step-by-step explanation:
To solve this question,we will have to understand some symbols in mathematics...
For example,* means ×
/ Means÷
We have so many of them
So back to the question
2*2^3 means 2 multiply by 2 raise to the power of 3
So 2^3 is 8
Therefore,2*8 means 2×8
It equals to 16
Therefore the final answer is 16
I hope you understand it better now
 
        
             
        
        
        
Answer:-tan (50) -tan (0) - tan (50) tan (0)
Step-by-step explanation:
any expression divided by one stays the same; simplify the expression using the symmetry of trigonometric functions.
 
        
             
        
        
        
Answer:
Piper traveled 115 miles for 6 hours.
Step-by-step explanation:
We just add the amount of distance that Piper traveled together, so "55+60 = 115 miles" and then we add the amount of time it took to travel that distance. So "3.5 + 2.5 = 6 hours".
