If x represents a number, then write an expression for a number that is three more than the number



Answer :

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! :)

Watch this carefully, before it's gone:

The expression for " three more than 'x' " is . . . . . ( x + 3 )  .

Did you see it go by ?
Here it is again:

The expression for " three more than 'x' " is . . . . . ( x + 3 )  .
