Stella had 30 minutes to do a three-problem quiz. She spent 9 7/10 minutes on question A and 5 2/5 minutes on question B. How much time did she have left for question C?

14 9/10 mins left

Step-by-step explanation: 9 7/10 + 5 2/5 five and two fifths=5 4/10 9+5=14

7/10+4/10=1 1/10 1 1/10+14=15 1/10 30-15 1/10=14 minutes and 54 seconds

the discriminant is 64 + 4*1*12 = 112

this is prime.
