Saying "a number" is the same as saying "x"
"Three more than a number" is the same as "three more than x"
If you have three more of something (say, marbles) than someone else, then you have their number of marbles plus three more.
Then, "Three more than x" is the same as "three plus x", or "3 + x"
Hope this helps! :)
The answer is 1, each number has 8 added to it.
Also, i hated IXL so goodluck-
Obviously, 0.8, all you do is move over the decimal.
The answer I got was 59.2
How I got it was that I counted how many years it was I got 16 years multiplied it by 3.7 and got 59.2
