The answer is 1.3. You round 1.3056 by using place value.
Well (5 x -10^6) is -5000000 and ( 4 x 10^3) is 4000 so then you have to do -5000000 / 4000. You can cross out the zeros to get -5000 / 4 which gets you -1250 so the answer is -1250.
Consider the operation is .
Given:
The augmented matrix below represents a system of equations.
To find:
Matrix results from the operation .
Step-by-step explanation:
We have,
After applying , we get
Therefore, the correct option is A.
6d -11/2 = 2d -13/2
Subtract 2d from both sides
6d -11/2 - 2d = 2d -13/2 - 2d
Simplifying
4d -11/2 = -13/2
Add 11/2 to both sides
4d -11/2 + 11/2 = -13/2 + 11/2
Simplifying
4d = -2/2
4d = -1
Divide both sides by 4
4d/4 = -1/4
Simplifying
d = - 1/4
