Answer:
To decide whether to add or subtract, determine if the values of the coefficients are the same or opposites:
. If the values are the same, subtract the equations.
• If the values are opposites or additive inverses, add the equations.
Step-by-step explanation:
Given
Required
How to solve
Options (1) and (2) are incorrect because none of the options eliminate x or y.
For option (3),
- Check for the coefficients of x and y
- If they are the same (sign and value), then subtract; otherwise add
For instance:
Rewrite the second equation
The coefficient of y are the same, so we subtract;
<em>See that y has been eliminated</em>
Answer:
the first one
2 to the power of 20 divided by 3 to the power of 8
Answer:
I think you have to subtract the to known numbers get the measurements between them.
Step-by-step explanation:
For example, 22 - 11 = 11 so the line segment with the question mark would be 11
I think :)
sorry if I'm wrong
Good luck
Note: Let us consider, we need to find the and .
Given:
In the given figure, BD is the angle bisector of ABC.
To find:
The and .
Solution:
BD is the angle bisector of ABC. So,
Divide both sides by 2.
Now,
And,
Therefore, and .
