For this case we must solve the following system of equations:

We multiply the first equation by -2:

We add the new equation with the second one:

We have different signs subtracted and the sign of the major is placed:

Now we find the value of the variable "y":

Thus, the solution of the system is given by:

Answer:

Answer:
$16.20 30% of 50 is 15 so divide 4 in the mix
The total percentage of the equation is 1,597.72
Given:
Area of rectangle =
sq. feet.
Width of the mirror =
feet.
To find:
Whether it will fit on the wall whose length is 5 foot.
Solution:
We know that, area of a rectangle is


Substituting the given values, we get






So, length of mirror is 4.75 feet which is less than 5 feet.
Therefore, the mirror will fit on the wall.
Answer:
A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n - 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n - 2) * 180 / n.
Step-by-step explanation:
There ya go.. :)
