Nestor the clown does the face painting at the city carnival. she paints seven faces every 21 minutes and spend the same amount of time each face right in equation that reflects f, the number of faces she paints and m, the time she spends painting in minutes

21/F=M

Step-by-step explanation:

3 minutes per face so divide time and faces to get the time.

F=7  M=3

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
