Explanation:
I don't really know why, but I answered a guess and got it correct, so If you trust me and what I am saying you will get the correct answer. However, If you don't trust me I completely understand why, but hope you use my answer anyway. Hope this can help you. If it doesn't please forgive me and the website I used.
Answer:
it is worked out that if 5 ladles full soup are given to each person 300 at a time
The product of the matrices is an identity matrix. Then Both the matrices are multiplicative inverse to each other.
<h3>What is the matrix?</h3>
A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The a_{ij} element in a matrix, such as M, refers to the i-th row and j-th column element.
The matrices are given below.
![\left[\begin{array}{ccc}-3&7\\-2&5\end{array}\right] \ and \ \left[\begin{array}{ccc}-5&7\\-2&3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-3%267%5C%5C-2%265%5Cend%7Barray%7D%5Cright%5D%20%5C%20%20and%20%5C%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-5%267%5C%5C-2%263%5Cend%7Barray%7D%5Cright%5D)
Then show that both the matrices are multiplicative inverse to each other.
If the product of the matrices is an identity matrix then the matrices are multiplicative inverse to each other.
Then we have
![\left[\begin{array}{ccc}-3&7\\-2&5\end{array}\right] \left[\begin{array}{ccc}-5&7\\-2&3\end{array}\right] = \left[\begin{array}{ccc}1&0\\0&1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-3%267%5C%5C-2%265%5Cend%7Barray%7D%5Cright%5D%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-5%267%5C%5C-2%263%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%5C%5C0%261%5Cend%7Barray%7D%5Cright%5D)
Then both the matrices are multiplicative inverse to each other.
