Final answer:
D. 10.The correct answer, D. 10, is determined by following the order of operations (PEMDAS/BODMAS) and carefully evaluating each step of the given mathematical expression.
Step-by-step explanation:
To decipher the expression "9 cookies divided by 1 plus 17 add 8 to the nine and divided by 2," we employ the order of operations (PEMDAS/BODMAS).
Firstly, within the parentheses, we add 17 and 8, resulting in 25. The expression now reads "9 cookies divided by 1 plus 25 divided by 2." Proceeding with division, 9 divided by 1 equals 9, and 25 divided by 2 yields 12.5.
The expression is now simplified to "9 plus 12.5." Combining these values, we get 21.5. Lastly, 21.5 is divided by 2, leading to the final answer of 10.
In summary, by adhering to the order of operations and carefully evaluating each component, we derive the solution. The correct interpretation of the given mathematical expression is 10.
