Answer:

3/4m + 1/2f ≤ 30
f ≤ 30

Step-by-step explanation:

Math session = 45 min = 3/4 hr
French session = 30 min = 1/2 hr
Number of math sessions = m, total math hours = 3/4m
Number of French sessions = f, total French hours = 1/2f

Total hours constraint:

3/4m + 1/2f ≤ 30

Number of session constraint:

f ≤ 30

So the system is:

3/4m + 1/2f ≤ 30
f ≤ 30
