Find the value of x
14x-15 and 139 degrees (look at the image)

x=4

Step-by-step explanation:

Simplifying

(14x + -15) + 139 = 180

Reorder the terms:

(-15 + 14x) + 139 = 180

Remove parenthesis around (-15 + 14x)

-15 + 14x + 139 = 180

Reorder the terms:

-15 + 139 + 14x = 180

Combine like terms: -15 + 139 = 124

124 + 14x = 180

Solving

124 + 14x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-124' to each side of the equation.

124 + -124 + 14x = 180 + -124

Combine like terms: 124 + -124 = 0

0 + 14x = 180 + -124

14x = 180 + -124

Combine like terms: 180 + -124 = 56

14x = 56

Divide each side by '14'.

x = 4

Simplifying

x = 4

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
