We know that
• The quarterback backs yo 5 yards (negative number).
,
• He falls back another 6 yards more (negative number).
To know the total number of yards the quarterback felt back, we just need to sum these negative numbers.
![-5-6=-11](https://img.qammunity.org/2023/formulas/mathematics/college/7hkq7372vgxti51wcjj4ga8brfosqzv7sr.png)
Therefore, the right answer is -11 yards.
