1 answer:
4 consecutive odd numbers....x, x + 2, x + 4, x + 6 2(x + x + 2) = 3(x + 4 + x + 6) - 40 2(2x + 2) = 3(2x + 10) - 40 4x + 4 = 6x + 30 - 40 4x + 4 = 6x - 10 4x - 6x = -10 - 4 -2x = - 14 x = -14/-2 x = 7 x + 2 = 7 + 2 = 9 x + 4 = 7 + 4 = 11 x + 6 = 7 + 6 = 13 ur numbers are : 7,9,11,13 <==

Answer:
125 adults
175 children
Step-by-step explanation:
3900=8c+20a
300=c+a
c=300-a
substitute
3900=8(300-a)+20a
reduce
3900=2400-8a+20a
1500=12a
a=125 adults
substitute for a
c=300-a
c=300-125
c=175 children
