Answer:
x= 54
Step-by-step explanation:
-9=x/-6
x-6 on both sides
54= x
Answer: It depends on the mean absolute deviation of Samantha.
Avi has a mean absolute deviation (MAD) of 5. That means the average distance of Avi's score from her mean is 5 points.
If Samantha has a higher MAD, that means that she is less consistent. If Samantha has a lower MAD, that means she is a more consistent scorer than Avi.
Answer:
Side A = 11
Side B = 16
Side C = 25
I added an image that shows what I did in case you need it.
The answer is x=-6.33333 (-19/3)
First, add like terms (12+7), which would equal to 19.
Then isolate the variable by subtracting 19 and adding it to the other side of the equal sign.
Now with this new equation of 3x=-19, isolate again by dividing 3 from x and do the same thing to the other side (-19/3).
The answer should be -6.33 repeating, but in algebra you would give a more simplified answer. This would be -19/3
ANSWER
We need to add half the coefficient of 
all square.
EXPLANATION
Given the equation,
.
We compare to the general equation,
This means that;
To complete the square we add, 
That is 
.
Hence the number to be added to both sides is .
Note that before we complete the square, the coefficient of the term in
must always be 1.
