Any singular matrix (a matrix with zero determinant) has no inverse.
The number is 2
9 x 2 = 18
18 + 6 = 24
Using the substitution method to solve the linear system the value of x and y is 1 and 2 respectively.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width.
Given
The equations are shown below.
y = 5 - 3x .....1
5x - 4y = -3 .....2
Substitute equation 1 in equation 2. Then
Then substitute the value of x in equation 1.
Thus, the value of x and y is 1 and 2 respectively.

Answer:
The area of base of cereal box is 20 mm².
Step-by-step explanation:
The volume of a cereal box is 400 mm³. The height of bx is 20mm.
The volume of box is
Divide both sides by 20.
Therefore the area of base of cereal box is 20 mm².
