Answer:
The inequality x + 3 < 12 can be used to determine the number of miles left to jog.
Step-by-step explanation:
It is given that:
Number of miles Beth has already jogged = 3 miles

x + 3 - 3 < 12 - 3
x < 9
Therefore,
The inequality x + 3 < 12 can be used to determine the number of miles left to jog.
