1) Open up any parentheses if there are any
2) Combine like terms (moving the variable to one side and other numbers to the other)
3) solve using pemdas/bedmas and any additional steps you need to isolate the variable
4) if x turns out negative, invert the sign
Example:
2x+5=3(x+1)
Open up the parentheses by multiplying it by 3
2x+5=3x+3
Combine like terms
2x-3x=3-5
-x=-2
x=2

The most accurate would be the second statement: <span>The graph is misleading because it uses 3-dimensional bars.
The vertical range is just enough. It only appears small because the bars are in 3D. It should have been in 2D so that we could directly trace it to how much frequency each category is. Even the axes are in 3D also.</span>
A small outlier could affect the whole data set because it could reduce the mean, or make the average of the whole data set smaller.
An example would be the data set could be 1, 8, 9, 10
To find the mean you would add everything together then divide it by the number of numbers you just added together. The mean of this set would be 28/4 which equals 7. Now, if the outlier were -8 instead of 1, then the mean would be much different.

Given that, a bike wheel is 26 inches in diameter.
We need to convert bike wheel's diameter in millimeters .
Since, 1 inch = 25.4 millimeters.
So, to convert 26 into mm we need to multiply 26 each sides of this identity to convert this into mm. Hence,
1*26 inch = 25.4 * 26 mm.
So, 26 inches = 660.4 mm.
So, the bike wheel's diameter is 660.4 millimeters.
Hope this helps you!
