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

Answer: 3H+4C<_ 30

The coefficients of the variables H and C represent the number of batteries each toy helicopter and each toy car uses.

Step-by-step explanation:

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

Now let's check whether Vugar has enough batteries for 5 toy helicopters and 4 toy cars. To do this, we substitute  H=5 and C= 4 in the given inequality:

Does Vugar have enough batteries to play with 5 toy helicopters and 4 toy cars?

No, because if you plug in the value for H and C:

3H + 4C<_ 30

3(5) + 4(4) <_30

15 + 16 <_ 30

31 <_ 30; false

Since the inequality is false, Vugar does not have enough batteries to play with 555 toy helicopters and 444 toy cars.

Each toy helicopter uses 333 batteries, and each toy car uses 444 batteries.

No, Vugar does not have enough batteries to play with 555 toy helicopters and 444 toy cars.

Answer 2

Answer:

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
