The expression 2+x represents a number. This number can be located on a number line. When is 2+x located to the right of 2? When is it located to the left of 2?

So shell be able to make about ten s'mores because 20÷2 is ten and it also depends how she's making the s'mores. for example if she gets a cracker and puts a Marsh mellow in the middle she'd be able to make 20 s'mores. or you can just break the cracker and half and make 40. I hope this long answer helped :)
