Jabari is thinking of three numbers. The greatest number is twice as big as the least number. The middle number is three more than the least number. The sum of the three numbers is 75. Find the numbers.

Answer 1

In this case, use variables to represent the numbers. Fortunately, they are all in terms of the smaller number. So, let...

x = small number
(x + 3) = middle number
2x = large number

If the sum is 75, then all of the numbers added together must equal this. So...

x + (x+3) + 2x = 75
4x + 3 = 75
4x = 72
x = 18

After we find x, we can conclude that...

Smaller number = 18
Middle number = 21
Large number = 36

Answer 5

But can you solve for X. that is the question on my paper what is x

Answer 6

Yes, I did this question on CPM, and my thought process was: Greater than 10, Less than 20, Greater than 15, So, then I got 18 for my final answer.
