<h3><u>The value of x is equal to 1.</u></h3><h3><u>6(x + 2) = 20x - 2</u></h3>
<em><u>Distributive property.</u></em>
6x + 12 = 20x - 2
<em><u>Add 2 to both sides.</u></em>
6x + 14 = 20x
<em><u>Subtract 16x from both sides.</u></em>
14 = 14x
<em><u>Divide both sides by x.</u></em>
x = 1
The answers should be: (-2,5), (-2,-2), (-6,-1), (2,1)
Hope this helped :)
The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean.
The MAD implies that Evelyn scores are more spread out than Robin scores.
The given parameters:
- <em>Robin scores = 99, 108, 102, 107 119</em>
- <em>Mean of Robin score, = 107</em>
- <em>Mean absolute deviation = 5.2</em>
- <em>Evelyn scores = 125, 137, 138, 145</em>
- <em>Mean of Evelyn score = 5.6</em>
The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean. It implies the absolute distance from the mean of the data set.
The absolute distance of Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.
Thus, we can conclude that Evelyn scores are more spread out than Robin scores.

Answer:
Step-by-step explanation:
Perform the indicated multiplication first:
25000 - 500bx + 50ax - abx²
It would seem that this should be part of an equation, and that the other part is missing; without another part, there's no way to determine the values of a and b. Please ensure you have copied this problem down completely.
As created (the concept) by Descartes, a variable is an alphabetic character used to represent unknown values. They are extremely useful when solving algebraic calculations allowing us to solve a range of calculations in simpler computations.
