Answer:
B
Step-by-step explanation:
To solve for x, we have to get x by itself. To do this, perform the opposite of what is being done to the equation.
5x+14=k
First, subtract 14 from both sides, because 14 is being added on to 5x. Subtraction is the opposite of addition.
5x+14-14=k-14
5x=k-14
Now, divide both sides by 5, because 5 and x are being multiplied. Division is the opposite of multiplication.
5x/5=k-14/5
x=k-14/5
So, the correct answer is choice B
x=12
x/16-1-4=1/2
multiply by both sides
x-4=8
move constant to the right side of and change its sign
x=8+4
add the numbers
x=12
Answer:
The Median is 20
Arrange the numbers in order
15 20 20 22 25
The middle number is 20
Set 1: {25, 26, 27, 27, 25, 27, 28, 26, 29, 30} Set 2: {20, 28, 26, 26, 30, 24, 25, 26, 28, 27} Round to the nearest tenth, if n

Set 1 Mean is 27 because it occurs most in the numbers and is the most common "in between" numbers.
Set 1 MAD, ( mean absolute deviation ), is 1.2
____________________________________________________________
Set 2 the mean is 26 (this number is also the median and mode)
Set 2 MAD is 1.8
I hope this helps you out :)
