Answer:
(B) a square matrix
Step-by-step explanation:
The given Equations are:
,
and

Which can be written as:
![\left[\begin{array}{ccc}3&-2&2\\7&3&-26\\-1&-11&46\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%26-2%262%5C%5C7%263%26-26%5C%5C-1%26-11%2646%5Cend%7Barray%7D%5Cright%5D)
Thus, it is a matrix with 3 number of rows and 3 number of columns, therefore the matrix which has same number of rows and columns is a square matrix, thus, a square matrix can be form using the given system of linear equations.
Answer:
36 minutes
Step-by-step explanation:
2/3 = 40 minutes
1/2 = 30 minutes
14/15 = 56 minutes
= 126 minutes
They were supposed to get picked up after an hour and a half, 1:00 - 2:30, which is 90 minutes. Subtract 90 from 126 because 126 is their total time out and 90 is the supposed time. Your answer is 36.
