Answer:
-2
Step-by-step explanation:
The least common multiple of each is 120
Answer: There are 14 students not taking any foreign languages.
Step-by-step explanation: Take the total number of students and subtract it by the number of students who are taking each class. So you would get 19 for French, 12 for Spanish, and 7 for both. Then you would add those numbers up and get a total of 38. You would then do the same except subtract each total of students by 30 to find how many of the 30 are not taking each class or both. You would then get 11 for French, 18 for Spanish, and 23 for both. Add those numbers up and get 52. Then you would subtract 38 from 52 thus giving the final answer 14.
