Answer:
11.5 hours
Step-by-step explanation:
25 pages every 75 minutes (1 1/4)
Thats means 1 page every 3 minutes (divide 25 and 75 by 25 to get this)
230 pages would mean 690 minutes (times the 3 by 230)
690/6 = 11.5
Answer:
A) Y=1/3x+6
Step-by-step explanation:
1. Subtract 6 from both sides.
-6 = 1/3 x
2. Divide 1/3 from both sides.
x = -18
The greatest common divisor of these numbers is 12.

Step-by-step explanation:
Answer: Matrix B is non- invertible.
Step-by-step explanation:
A matrix is said to be be singular is its determinant is zero,
We know that if a matrix is singular then it is not invertible. (1)
Or if a matrix is invertible then it should be non-singular matrix. (2)
Given : A and B are n x n matrices from which A is invertible.
Then A must be non-singular matrix. ( from 2 )
If AB is singular.
Then either A is singular or B is singular but A is a non-singular matrix.
Then , matrix B should be a singular matrix. ( from 2 )
So Matrix B is non- invertible. ( from 1 )
