A concert hall has three sections: the main floor, the balcony, and the gallery. For a recent concert, 1020 tickets were sold. There were twice as many balcony tickets sold as gallery tickets, and 225 more main floor tickets than balcony tickets. If g represents the number of gallery tickets sold, which expressions represents this situation? a. Gallery: g b. Gallery: gg225 Balcony: 9 Balcony: 2g Main Floor: g 225 Main Floor: g c. Gallery: g d. Gallery: g Balcony: g+225 Balcony: 2g Main Floor: 2g+225 Main Floor: 2g 225

the expressions that represents this situation is

Gallery: g

Balcony: 2g

Main floor: 2g + 225

Step-by-step explanation:

Let g represent the number of gallery tickets that were sold,

The concert hall has three sections: the main floor, the balcony, and the gallery. There were twice as many balcony tickets sold as gallery tickets. This means that the number of balcony tickets is 2g.

There were 225 more main floor tickets than balcony tickets. This means that the number of main floor tickets that was sold is

2g + 225

The total number of tickets that were sold at the concert is 1020. This is expressed as

g + 2g + 2g + 225 = 1020

this doesn't make sense lol

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
