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 shortest side would
Be 18.
64 -18 = 46
46 divided by 2 = 23.
So if two of the sides was the same 18 would be the smallest one of the sides could be
Probability of an event= number of ways an event can occur / total number of possible outcomes.
Probability = 6/12 = 0.5
I got x = -.3 repeating. 2x2 = 4 + 3x=-5 u then -4 from each side and you get 3x = -1. divide both sides by 3 and you get x= -.3 repeating.
