Final answer:
The equation representing the number of throws Peyton needs to make to match Tom's yards is 9x + 250 = 11x + 120.
Step-by-step explanation:
To find the equation representing the number of throws Peyton needs to make in order to match the number of yards thrown by Tom, we can set up the following equation:
9x + 250 = 11x + 120
Where x represents the number of throws made by Peyton. By simplifying the equation, we can find the value of x, which will tell us how many throws Peyton needs to make.
Therefore, the correct answer is a. 9x + 250 = 11x + 120.
