Answer:
5x<12
Explanation:
For this equation we will assume that x is the number of minutes it takes Todd to swim one lap.
To write an equality for this, we want the total amount of time it takes to be less than twelve minutes, so 5*x must be less than 12.
To write an equality for this, we will start with 5*x, the use the less than symbol < (not less than or equal to) which will give us our answer of 5x<12.
