Given:
On three consecutive passes, a football team gains 10 yards, loses 19 yards, and gains 21 yards.
To find:
An addition fact that corresponds to the given sentence and the number represents the total net yardage.
Solution:
It is given that first football gains 10 yards then loses 19 yards and then again gains 21 yards.
The gaining is shown by a positive sign and the loss is shown by a negative sign.
So, the addition fact is given below:
[tex]+10-19+21[/tex]
Now, the resultant of the above expression is the total net yardage.
[tex]\begin{gathered} +10-19+21=+31-19 \\ =+12 \end{gathered}[/tex]
Thus, the total net yardage is 12 yards.
