One number is eight times the first number a third number is 100 times more than the first number if the sum of the three numbers is 840 find the numbers

Step-by-step explanation:

The equations would look like this:

x + 8x + x + 100 = 840

Combine like terms.

10x + 100 = 840

Subtract 100 from each side.

10x = 740

Divide both sides by 10.

x = 74

So, that makes one of the numbers 74.

Now, we're gonna substitute 74 into 8(x) to find the second number.

8(74) = 592

So, the next number is 592.

592 + 74 = 666

840 - 666 = 174

So, the numbers are 74, 592, and 174

If you'd like to check the answer, plug the numbers back into the equation:

74 + 8(74) + 74 + 100 =

840.
