Final answer:
The largest whole number x could be for the inequality 9+x > 2x to hold true is 8, as this satisfies the inequality with 17 being larger than 16.
Step-by-step explanation:
The question asks to find the largest whole number x such that 9 + x is larger than 2x.
To solve for x, we can set up the inequality as follows:
9 + x > 2x
Subtract x from both sides of the inequality to isolate x on one side:
9 > x
Therefore, the largest whole number that x could be is 8, because 9 + 8 = 17, which is indeed larger than 16 (which is 2 times 8).
