Answer 1

В походе (путешествии) мальчиков на 5 больше, чем девочек. учителей в 2 раза больше, чем девочек. не считая девочек, всего 29 человек в походе. сколько всего человек в походе?

Answer 2

Let's break down the information given:

1. There are 5 more boys than girls on the trip.
2. There are twice as many teachers as girls on the trip.
3. Not counting the girls, there are 29 persons on the trip.

Let's denote:

• Let "G" be the number of girls.
• Let "B" be the number of boys.
• Let "T" be the number of teachers.

From the first piece of information, we know that: B = G + 5

From the second piece of information, we know that: T = 2 * G

From the third piece of information, we know that: B + T = 29 (since not counting the girls, there are 29 persons in total)

Now we can substitute the values of B and T from the equations above:

(G + 5) + 2 * G = 29

Combine like terms: 3G + 5 = 29

Subtract 5 from both sides: 3G = 24

Divide by 3: G = 8

Now that we know there are 8 girls, we can find the values for boys and teachers:

B = G + 5 = 8 + 5 = 13 T = 2 * G = 2 * 8 = 16

So, there are 8 girls, 13 boys, and 16 teachers on the trip, making a total of 8 + 13 + 16 = 37 persons altogether.
