Juliette [100K]

Answer:

50km per hour

Step-by-step explanation:

When you think of average speed it would be per hour, so when thinking 30 minutes is .5 of a hour that means when you add 30 minutes and 30 minutes you get 1 hour so you would add 25km and 25km and you would get its average speed per hour, I hope that made sense

Help! I'm a little stumped when it comes to variables in matrices. An explanation would be super rad!
iris [78.8K]

Answer:

30

Step-by-step explanation:

To find the determinant of a 3x3 matrix, you can use this method. (See picture.)

Start with the first number in the top row, and block off the row and column.  A 2x2 matrix will be left.  Find the determinant of this 2x2 matrix, and multiply it by the number in the top row.

Repeat for the other two numbers in the top row.  Add the first result, subtract the second, and add the third.

det A = -2 [(3)(-5) − (a)(0)] − 2 [(0)(-5) − (a)(0)] + b [(0)(0) − (3)(0)]

det A = -2 (3)(-5) − 0 + 0

det A = 30
