1 answer:
The solution of the equation is x = 0 and y = 8.
Given
The system of equation is;
Any system of equations can be solved in different methods. To solve a system of equations in 2 variables, we need at least 2 equations following all the steps given below.
From equation 1
Substitute the value of y in equation 2
Substitute x = 0 in the equation 1
Hence, the solution of the equation is x = 0 and y = 8.

Given:
The area of the squares are given.
To find:
The exact side length or estimate side length of the square.
Solution:
We know that, the area of a square is
Where, a is the side length of the square.
Area of the square is 100 square units. So, the side length is:
Therefore, the side length is 10 units.
Area of the square is 95 square units. So, the side length is:
It is not exact. We know that .
Therefore, the side length is between 9 and 10.
Area of the square is 36 square units. So, the side length is:
Therefore, the side length is 6 units.
Area of the square is 30 square units. So, the side length is:
It is not exact. We know that .
Therefore, the side length is between 5 and 6.
so you take the average of the x coordinates and the average of the y coordinates to get the midpoint like this
