Question

У Пеппи и Моанны одинаковое число жемчужин для игры в шарики, а у Томми жемчужин в два раза меньше, чем у Пеппи. Всего же у них троих 200 жемчужин. Сможет ли Томми на свои жемчужины выменять у рыбаков ожерелье из акульих зубов, если за одно ожерелье надо отдать 10 жемчужин?

Answer 1

пусть у томми- x жемчужин, тогда у пеппи-2x жемчужин, а у моанны- 2x. в задании сказано, что их сумма= 200 жемчужинам составим и решим уравнение:

x+2x+2x=200

5x=200

x=40

 

40-10=30

ответ:да сможет.

Answer 2

80-у  пеппи и моанны

вместе 160 значит у томми 40 и она сможет купить

Answer 3

Problem Analysis

We are given the following information: - Peppa and Moana have the same number of pearls for playing with marbles. - Tommy has half the number of pearls as Peppa. - The total number of pearls among the three of them is 200. - Tommy wants to exchange his pearls for a necklace made of shark teeth, which costs 10 pearls.

We need to determine if Tommy can exchange his pearls for the shark tooth necklace.

Solution

Let's solve this problem step by step.

1. Let's assume the number of pearls Peppa and Moana have is P. 2. According to the given information, Tommy has half the number of pearls as Peppa, so Tommy has P/2 pearls. 3. The total number of pearls among the three of them is 200, so we can write the equation: P + P + P/2 = 200. 4. Simplifying the equation, we get: 2P + P/2 = 200. 5. Combining like terms, we have: (4P + P)/2 = 200. 6. Simplifying further, we get: 5P/2 = 200. 7. Multiplying both sides of the equation by 2/5, we get: P = 80. 8. Now that we know the number of pearls Peppa and Moana have is 80, we can find the number of pearls Tommy has: P/2 = 80/2 = 40.

Therefore, Peppa and Moana each have 80 pearls, while Tommy has 40 pearls.

Now, let's determine if Tommy can exchange his pearls for the shark tooth necklace. Tommy needs to give 10 pearls for the necklace. Since Tommy has 40 pearls, he can exchange them for the necklace because 40 is greater than 10.

Conclusion

Tommy can exchange his pearls for the necklace made of shark teeth because he has enough pearls.
