A+c=100
3a+2c=275, from the first c=100-a making the 2nd equation become:
3a+2(100-a)=275 perform indicated multiplication on left side
3a+200-2a=275 combine like terms on left side
a+200=275, subtract 200 from both sides
a=75, and since c=100-a
c=100=75=25
So the answer is D. 25 children and 75 adults
Equation 1: a+c=100
Equation 2: 3a+2c=275
Answer:
y = 1

Step-by-step explanation:
n = 0 : 2(0) -1 = -1
n = 1 : 2(1) - 1 = 1
n = 2 : 3
n = 3 : 5
n = 4 : 7
n = 5 : 9
sum = -1 + 1 + 3 + 5 +7 + 9 = 25
