Question

Vugar has a maximum of 30 batteries for toys. Each toy helicopter uses the same number of batteries, and each toy car uses the same number of batteries. Let H represent the number of toy helicopters and C represent the number of toy cars that Vugar can play with without running out of batteries. 3H+4C?303 According to the inequality, how many batteries does each toy helicopter use, and how many batteries does each toy car use? Does Vugar have enough batteries to play with 5 toy helicopters and 4 toy cars? Choose 1 answer: A) Yes B) No

Answer 1

Vugar does not have enough batteries to play with 5 toy helicopters and 4 toy cars.

Step-by-step explanation:

To find out how many batteries each toy helicopter and toy car use, we need to solve the equation 3H+4C≤30, where H represents the number of toy helicopters and C represents the number of toy cars. Let's rewrite the equation with the given inequality: 3H + 4C ≤ 30. Since we have 5 toy helicopters and 4 toy cars, we can substitute these values into the inequality: 3(5) + 4(4) = 15 + 16 = 31. Since the sum is greater than 30, Vugar does not have enough batteries to play with 5 toy helicopters and 4 toy cars. The answer is B) No.

Answer 2

Each toy helicopter uses 3 batteries, and each toy car uses 4 batteries.

B) No, Vugar does not have enough batteries to play with 5 toy helicopters and 4 toy cars
