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 + 40 < 30

According to the inequality, how many batteries does each toy helicopter use, and how many batteries does

each toy car use?

Each toy helicopter uses

batteries, and each toy car uses

batteries.

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

Abel Mathews · Answer 1

Step-by-step explanation:

3H + 4C < 30

each toy helicopter uses 3 batteries ... because 3H ... with H being the number of helicopters ... this is telling us that each helicopter uses 3 batteries

each toy car uses 4 batteries ... because 4H ... with H being the number of toy cars ... this is telling us that each toy car uses 4 batteries

does he have enough batteries for 5 helicopters and 4 cars?

Lets find out ... sub in 5 for H and 4 for C

3H + 4C < 30

3 (5) + 4 (4) < 30

15 + 16 < 30

31 < 30 (incorrect) ... NO, he does not have enough ... he is short 1 battery
