Species A: 18.9 miles / 42 minutes = 0.45 miles per minute
Species B: 20.3 miles / 58 minutes = 0.35 miles per minute
Therefore, species A is faster and flies at a speed of 0.45 miles per minute
(27 mph)
0.45 x 60 = 27 mph
The answer is 45, because if you have 45(x)-15(y)=30
Answer:
[2 5 0]
[-7 -11/2 12]
Step-by-step explanation:
We want to perform elementary row operation represented by R2 - ½R1 on matrix A in the figure attached.
Now, matrix A is given as;
[2 5 0]
[-6 -3 12]
Now, R1 is row 1 = [2 5 0]
R2 is row 2 = [-6 -3 12]
Thus, R2 - ½R1 = [-6 -3 12] - ½[2 5 0]
This gives;
[-6 -3 12] - [1 5/2 0] = [-7 -11/2 12]
Now,[-7 -11/2 12] will be the new row 2 since it's just an elementary row operation we did on the Matrix A.
Thus, the new matrix is now;
[2 5 0]
[-7 -11/2 12]
