2is added to twice a certain number and the sum is doubled .the result is 10 less than 5 times the original number

14

Step-by-step explanation:

2(2n + 2)= 5n - 10

4n + 4 = 5n - 10

n=14

2 is added to twice a certain number and the sum is doubled. The original number is 14

Solution:

Let x be the original number

Given that the 2 is added to twice of x. This can be represented as (2 + 2x)

Now it is given that the sum is doubled which means 2(2 + 2x)

The result is 10 less than 5 times the original number "x" which means 2(2 + 2x) = 5x - 10

The above expression is solved to get the value of original number

2(2 + 2x) = 5x - 10

4 + 4x = 5x - 10

On rewriting the above expression, we get

5x - 10 -4 -4x = 0

x - 14 = 0

x = 14

Hence the original number is 14

step-by-step explanation:

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
