Answer: Option B is correct.
Step-by-step explanation: To answer this question accurately, we first must solve for x in the inequality.
First, we rewrite the problem:
[tex]2x \ + \ 20 \ < \ 43[/tex]
Next, we subtract 20 from both sides:
[tex]2x \ + 20 \ - \ 20 \ < \ 43 \ - \ 20\\2x \ < \ 23[/tex]
Finally, we divide by the coefficient (2):
[tex]\dfrac{2}{2} = 1\\\\\dfrac{23}{2} = 11.5[/tex]
We find our final inequality to be represented as x < 11.5. Because the tick mark between 10 and 12 on the number line represents 11, option B is correct because the dot is to the right of the tick mark but not on or greater than 12.
