To create an inequality in standard form for Brittany's workout time, we can set up the relationship based on the time it takes for each type of workout and the maximum time available.

Given:
- It takes 31 minutes for each cardio workout, represented by \( x \).
- It takes 21 minutes for each weightlifting workout, represented by \( y \).
- Brittany has a total of up to 453 minutes available for workouts.

The total time spent on workouts can be expressed as:
\[
31x + 21y \leq 453
\]

This inequality represents the constraint that the total time Brittany spends on cardio workouts and weightlifting workouts should not exceed 453 minutes.

Thus, the inequality in standard form is:
\[
31x + 21y \leq 453
\]
