Final Answer:
Amirah evaluated (279 - 38 = 241). She can check her answer by adding 38 to 241, which should result in the original number, 279.
Step-by-step explanation:
To verify Amirah's subtraction, we can add the result back to the subtrahend to ensure it equals the original minuend. In this case, adding 38 to the difference (279 - 38) should yield the original number, 279. Mathematically, this can be expressed as (241 + 38 = 279), confirming the accuracy of Amirah's subtraction.
The subtraction operation is essentially finding the difference between two numbers, and its inverse operation, addition, can be used to validate the result. Amirah subtracted 38 from 279, obtaining 241. Adding 38 to this result should bring her back to the starting point of 279. This approach serves as a straightforward method for checking the accuracy of subtraction and is a fundamental principle in arithmetic.
In summary, Amirah's evaluation of (279 - 38) as 241 can be verified by performing the inverse operation of addition. Adding 38 to the result should yield the original number, 279, thereby confirming the correctness of her subtraction.
