Answer:
7.75 or 7 3/4
Step-by-step explanation:
Divide 27 1/8 by 3 1/2 to find the length, because Length x Width = Area
When you divide, you get 7.75
This is the length.
You can also convert it into fraction form and get 7 3/4
The answer you want would be A
For this case we must find the solution of the following system of equations:

If we multiply the first equation by -2 we have the following equivalent system:

If we add the equations we have:

Thus, the system has infinite solutions.
Answer:
Infinite solutions
8.76582 × 10 to the 3rd power, that's how many hours there are in a year using scientific notation.
15 x 2 = 30 (this is the area)
15 + 15 + 2 + 2 = 34 (this is the perimeter)
Therefore the dimensions must be 15 and 2.
