Final answer:
To solve for the blank in the equation 2 - ⬚ = 43, one must subtract 2 from 43 to find that the solution is actually ⬚ = 41. None of the provided options are correct.
Step-by-step explanation:
The student is asking to solve the equation 2 - ⬚ = 43. To find the value of the blank box, we need to isolate it. To do so, we carry out the following steps:
- Subtract 2 from both sides of the equation to get ⬚ on one side and 43 - 2 on the other.
- Calculate the result of 43 - 2 to find the value of ⬚.
- The final step gives us ⬚ = 41.
Thus, none of the options (A) ⬚ = 30, (B) ⬚ = 30.5, (C) ⬚ = 60, or (D) ⬚ = 27.5 are correct. The solution to the equation is ⬚ = 41.
