Alittle pwease : o ? a group of 45 people attended a ball game. there were twice as many children as adults in the group. set up a system of equations that represents the numbers of adults and children who attended the game and solve the system to find the number of children who were in the group. o. o

30. Since there are twice as many children as adults, let's say the number of adults is x. That means the amount of children is 2x. You know that in total there are 45 people. This means that the number of adults plus the number of children is 45. So we can set up x + 2x = 45. We can solve for x. 3x = 45 so x = 15. Remember, as we stated before, x is the number of adults. 2x is the number of children. Since x = 15, 2x = 30 so there are 30 children in the group.

What do you mean by that?
