Part A
Ahat [919]

The augmented matrix for the system is:

\left[\begin{array}{cccc}3&1&1&43.75\\1&3&2&27.75\\2&2&1&34\end{array}\right]

--------------------------

For our system, we suppose that x is the number of tickets, y is the number of drinks and z is the number of bags of popcorn.

Devin bought <u>three tickets, one drink, and one bag of popcorn for $43.75.</u>

This means that:

3x + y + z = 43.75

Neil bought <u>one ticket, three drinks, and two bags of popcorn for $27.75</u>.

This means that:

x + 3y + 2z = 27.75

Jung bought <u>two tickets, two drinks, and one bag of popcorn for $34.</u>

This means that:

2x + 2y + z = 34

The system is:

3x + y + z = 43.75

x + 3y + 2z = 27.75

2x + 2y + z = 34

Which is represented by the following augmented matrix:

\left[\begin{array}{cccc}3&1&1&43.75\\1&3&2&27.75\\2&2&1&34\end{array}\right]

If a squared number is an irrational number, then how come I can only select one irrational number.
Julli [10]
They are both rational. This is because 3^2 is 9 and 9^2 is 81. Rational means that the number ends or repeats and 9 and 81 end.
