Three numbers added together total 500. the second number is four times the first, and the third is five times the second. find each number.

Okay, I believe if I am correct, I believe that the first number is 20, the second number is 80, and the third number is 400.

If you first get 20, you would multiply that by 4 to get 80
Now so far you have 20+80 which equals 1000

Now, if you multiply 80 w/ 5, you would get 4000
Now you have 100+400

Now you have 500!

I hope this helps

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
