Set it up like this, going from words on the page to letters and variables:
-3(2x+5) = -57. Twice a number is 2x, increased by 5 is 2x+5, and that is multiplied by -3 to get a total of -57. Distribute the -3 into the parenthesis to get -6x - 15 = -57. Move the 15 over by addition to get -6x = -42. Divide both sides by -6 to get that x = 7

Step-by-step explanation:
The question is incomplete, as the box plot is not attached.
However, the interpretation of the question is to determine the inter-quartile range (IQR) ; this represents the middle 50% of scores
To answer this question, I will make use of the attached box plot.
IQR is calculated as:
and 
are represented by the vertical edges of the rectangle in the box plot. [See attachment]
Reading and , we have:
The IQR is:
<em>Hence, the range that describes the middle 50% of the attached plot is 13</em>
