Answer:
Addition property justifies manipulation of the equations.
Step-by-step explanation:
Given:
Two equations.
⇒ 
...equation (i)
⇒ 
...equation (ii)
We have to identify the property which justifies the manipulation.
Note:
The Linear Combination Method:
- Adding (or subtracting) a multiple of one equation with the other equation, in such a way that either the x -terms or the y -terms cancel out.
- Then solve for x (or y) and substitute back to get the other values.
- Also known as the addition and the elimination method.
The above equation is following the linear combination method where x-values are added to find the y value.
Solving:
⇒ ...(i)
⇒ ...(ii)
⇒ <em>Adding both the equations.</em>
⇒ 
⇒ <em>Dividing both sides with 7.</em>
⇒ 
⇒ 
Addition property justifies manipulation of both the equations.

Answer:
Ten times as 8 hundreds is 8 thousands.
Step-by-step explanation:
Ten times as 8 hundreds is 8 thousands.
This can be written mathematically as:
10 times as 800, is 8000.
or, we can multiply these to get the answer.
So, the answer is : Ten times as 8 hundreds is 8 thousands.
Below are the choices:
<span>-1/2
0
-1
non
</span>
The exclusions are placed on the variable x for the fraction 4x^2-1/4x+2 is -1/2. Below is the solution,
<span>4x+2 = 0 so 4x=-2 so x=-2/4 wich is -1/2</span>
