Answer:
Students purchased 1296 tickets and teachers purchased 482 tickets.
Step-by-step explanation:
We are given the following in the question:
Let x be the number of tickets purchased by students and y be the number of tickets purchased by teachers.
Total tickets purchased = 1778
Thus, we can write the equation:
There are 150 students less than three times the number of teacher's tickets.
Thus, we can write the equation:
Solving the two equations, we get,
Thus, students purchased 1296 tickets and teachers purchased 482 tickets.
The cofactors of each entry in the first row of the matrix exist
We have to estimate the cofactors of each entry in the first row of the matrix.
<h3>What is the matrix?</h3>
A set of numbers exists arranged in rows and columns to create a rectangular array. The numbers exist named the elements, or entries, of the matrix.
Thus the cofactors of each entry in the first row of the matrix exist
