I do believe it is 12 as well considering the fact that it's negative three and not positive. If it was a positive three then maybe it would be 18.
The frequency distribution chart of the math quiz has a data that is skewed left.
<h3>How to interpret the shape of the histogram?</h3>
From the complete question (see attachment for histogram), we have the following highlight:
The dataset on the right-hand side is taller than those on the left.
This means that the dataset is skewed left.
Hence, the statement that best describes the data is (a) The data is skewed left.

#SPJ1
No it’s not because (6,2) would be a no solution so no
Because you're trying to make them congruent, equal the two expressions to each other.
So, for #10 you would equal them so it would look like this.
2x+2=5x-19
Then you would just go ahead and simplify
2x+2=5x-19
-2x -2x
---------------
2= 3x -19
+19 +19
---------------
21=3x
--- ----
3 3
x=7
This means that x should be 7. You can check this just by plugging it in
2x+2
2(7)+2 = 16
5x-19
5(7)-19= 16
Same with #11.
x+8=3x-14
-x -x
--------------
8=2x-14
+14 +14
--------------
22=2x
--- ----
2 2
x=11
Check.
x+8
11+8= 19
3x-14
3(11) - 14 = 19
