Answer:
26 Track practices
Explanation:
Janet has already run 12 miles on her own.
For each track practice, she expects to run 1 mile.
Let the number of track practices = x
Therefore, the total miles run after x track practices
[tex]=12+1x[/tex]
If her total miles run = 38 miles, then:
[tex]\begin{gathered} 12+1x=38 \\ x=38-12 \\ x=26 \end{gathered}[/tex]
It would take her 26 track practices to run 38 miles.
