Mark gave 21 tadpoles to his 3 friends. Mark gave twice as many tadpoles to David as he did Chris.George received twice as many
amm1812

Answer:

Number of tadpoles Chris has = 3

Number of tadpoles David has = 6

Number of tadpoles George has = 12

Step-by-step explanation:

Given: Total number of tadpoles divided among 3 friends = 21

Number of tadpoles Mark gave to Chris = A  

Number of tadpoles Mark gave to David = B = 2A

Number of tadpoles Mark gave to George = C = 2B = 2(2A) = 4A

∴ Total number of tadpoles = A + B + C

⇒ 21 = A + 2A + 4A

⇒ 21 = 7A

⇒ A = 21 ÷ 7 = 3

∴ Number of tadpoles Chris has = A = 3

Number of tadpoles David has = B = 2A = 2(3) = 6

Number of tadpoles George has = C = 2B = 2(2A) = 4A = 4(3) = 12

Which of the following sets show all the numbers from the set {3, 4, 5, 6} that are part of the solution to the equation 5x + 4
Vesna [10]

Replace x with the possible answers and solve to see which ones make the equation true:

5(3) = 15 + 4 = 19. 19 is < 29 so 3 works.

5(4) = 20 + 4 = 24. 24 is < 29, so 4 also works.

5(5) = 25 + 4 = 29. 29 is not less than 29 so doesn't work.

Only 3 and 4 will work.

The answer would be {3,4}

A group of teachers and students will take a bus trip to a museum, and each teacher will lead a group of no more than 4 students
ValentinkaMS [17]

Answer:

A maximum of 43 students and 11 teachers can go to the trip.

Step-by-step explanation:

Since a group of teachers and students will take a bus trip to a museum, and each teacher will lead a group of no more than 4 students, and the bus can hold a maximum of 54 teachers and students, to determine the possible numbers of teachers and students who can go on the trip, the following calculation must be performed:

4 + 1 = 5

54/5 = X

10.8 = X

10 x 4 = 40

10 x 1 = 10

4 - 1 = 3

Therefore, a maximum of 43 students and 11 teachers can go to the trip.
