10 times as many as a number is 10 × the number.
10 times as many as 1 ten is 10 × 10 = 100
10 times as many as 1 hundred is 10 × 100 = 1000
Therefore, 10 times as many as 1 hundred is 10 hundreds or
10 times as many as 1 hundred is one thousand.
This involves quite a lot of arithmetic to do manually.
The first thing you do is to make the first number in row 2 = to 0.
This is done by R2 = -3/2 R1 + R2
so the matrix becomes
( 2 1 1) ( -3 )
( 0 -13/2 3/2) (1/2 )
(5 -1 2) (-2)
Next step is to make the 5 in row 5 = 0
then the -1 must become zero
You aim for the form
( 1 0 0) (x)
(0 1 0) (y)
(0 0 1) ( z)
x , y and z will be the required solutions.

Answer:
A. -415m
Step-by-step explanation:
-300 meters is the starting point.
Then, the submarine goes 115m further below the surface, which can be represented as -115.
Add -300 and -115 and you get -415m.
