Answer:

1/9

Step-by-step explanation:

since 4 < a < 5, a= 4.5 and since 2 < b < 4, b=3

4.5/3(3) - 3/3(4.5)

then you can cross simplify and the 3s cancel out in the second half and the 4.5s cancel each other out leaving you with 1/3(3) which is 1/9

OlgaM077 [116]

Answer:

Step-by-step explanation:

Let c represent the number of children that attended the concert.

Let a represent the number of adults that attended the concert.

At one of the concerts, each adult brought 4 children with them, and 10 children attended without an adult. This means that the number of children that attended is

c = 4a + 10

Tickets for a concert were $5 for each child and $8 for each adult. The total ticket sales were $1730. It means that

5c + 8a = 1730

Therefore, the systems of equations that can be solved to determine the number of children, c, and adults that attended the concert is

c = 4a + 10

5c + 8a = 1730
