Answer:
x^2+15
Step-by-step explanation:
5 days food for 150 students suggests there was 750 day rations
If there was 100 students this would last 750/100 = 7.5 days.
If it ran out after 4 days there were 750/4 = 187 students (187.5 not valid)
What times 4 equals 24. Answer: 1/4 of 24 is 6, because 5x4=24.
P = kq/r
5 = k*1/2
k = 2*5 = 10
p = 5*10/50 = 1
P is 1.
Hope it helps!
Answer:
-15
Step-by-step explanation:
