<u>Given:</u>
The two equations are 
and 
We need to solve the equations using elimination method.
<u>Elimination method:</u>
Let us multiply the equation by 5, we get;
---------(1)
Now, multiplying the equation by -2, we get;
--------(2)
Adding equations (1) and (2), we have;
Thus, the value of y is 3.
Substituting in the equation , we have;
Thus, the value of x is 4.
Hence, the solution of the system of equations is (4,3)
Therefore, Option A is the correct answer.
The percentage shows that they were 28% more likely to come from Riverdale High school.
<h3>How to calculate the percentage?</h3>
From the information given, the percentage of those from Rockport will be:
= 25/(25 + 44) × 100.
= 25/69 × 100
= 36.23%
The percentage of those from Riverdale will be:
= 44/(25 + 44) × 100.
= 44/69 × 100
= 63.77%
Therefore, the difference will be:
= 63.77% - 36.23%
= 28% approximately.

Answer: The number of different ways she could arrange the carpet squares is 36!.
Step-by-step explanation:
We know that , the number of ways to arrange n things = n!
Given that , Your teacher has 36 carpet squares.
i.e. The total number of carpet squares = 36
If she needs to make a new arrangement for the reading carpet.
Then, the total number of arrangement of carpet squares would be 36!.
Hence , the number of different ways she could arrange the carpet squares is 36!
