Final answer:
The three related facts for 12-7=5 are: none. None of the other equations mentioned in the question provide the correct result of 5 when subtracting.
Step-by-step explanation:
To find related facts for 12 - 7 = 5, we need to determine other equations that also result in 5 when subtracting.
The subject of this question is basic mathematics, specifically the operation of subtraction. The equation presented, 12 - 7 = 5, is a simple subtraction problem where 7 is subtracted from 12 to result in 5. None of the choices provided for the equation are correct, because all of them lead to a result different from 5. In relation to the given equation, we could mention three related facts, such as:If you add the result (5) to the subtracted number (7), you will get the original number (12).If you subtract the result (5) from the original number (12), you will get the subtracted number (7).
The switch of numbers in subtraction does not provide the same result as in addition, meaning that the equation 7 - 12 would provide a negative result (-5), not 5.
Therefore, the correct option is d. None. None of the other equations mentioned in the question provide the correct result of 5 when subtracting.
