Lúcia e Antônio disputam várias partidas de um jogo no qual cada um começa com cinco pontos. Em cada partida, o vencedor ganha dois pontos e o derrotado perde um ponto, não havendo empates. Ao final, Lúcia ficou com dez pontos e Antônio ganhou exatamente três partidas. Quantas partidas eles disputam ao todo?

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
