Using cramer’s rule, what is the value of x in the system of linear equations below? 3x+4y=15 8x-2y=40

D) x=5

Step-by-step explanation:

Edge 2021 :)

We have to solve the system of equations by Cramer's rule.

The coefficient matrix is given by

Let us find the determinant of coefficient matrix.

For X-matrix

Now, we find its determinant

For Y-matrix

Now, we find its determinant

Therefore, the value for x is given by

The value for x is 5.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
