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.
The other polynomial addend, when the sum of two polynomials is 10a2b2 – 8a2b 6ab2 – 4ab is 15a²b²- 20a²b + 6ab² - 4ab + 7.
<h3>What is polynomial?</h3>Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).
The sum of two polynomials is,
The one polynomial addend is,
Let suppose the other polynomial addend is f(a,b). Thus,
Isolate the second polynomial as,
Arrange the like terms as,
Hence, the other polynomial addend, when the sum of two polynomials is 10a2b2 – 8a2b 6ab2 – 4ab is 15a²b²- 20a²b + 6ab² - 4ab + 7.
