Answer:
18.5 yards
Step-by-step explanation:
Tom's first carry was -5 yards and his second was +12.5 yards. If we know he finished with 26 yards we can make a simple equation to try and find the distance of his third carry. We let the letter be a variable that represents the distance of his third carry.
This means his first carry + second carry + third carry = carry total
We can simply the left hand side
Now we move the 7.5 to the right side by subtracting it.
So Tom's third carry was for 18.5 yards!
Hope this helps!
