The sum of three numbers is 12 . The sum of twice the first number, 3 times the second number, and 4 times the third number is 37 . The difference between 7 times the first number and the second number is 25. Find the three numbers.

Given:

The sum of three numbers is 12 .

The sum of twice the first number, 3 times the second number, and 4 times the third number is 37 .

The difference between 7 times the first number and the second number is 25.

To find:

The three number.

Solution:

Let the three numbers are x, y and z respectively.

According to the question,

          ...(i)

        ...(ii)

          ...(iii)

From (iii), we get

Put value in (i).

       ...(iv)

Put value in (ii).

         ...(v)

Now, Multiply equation (iv) by 4 and subtract the result from (v).

Put x=4 in (iv).

Put x=4 in .

Therefore, the three numbers are 4, 3 and 5 respectively.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

yes because they have the same amount of green and blur marbles.
