How do I write this in inequality?

The value of r is at most 10

and would it be an open or closed on the number line? I think open?

r ranges from -inf to 10
<----------O with the circle at 10.

r<=10
Yeah I got it right! thanks. I wasn't sure if I understood it or not. I did. Thanks!!
oh wait just making sure. Open circle? And you put =?

I have r , 10 open circle at 10 going left. Is it all right???

I have r < 10 open circle at 10 going left. Is it all right???
if r can be 10, it includes 10. Normally, open circles are points to be excluded. If it does not include 10, then open circle at ten. I am not certain if the problem includes ten or not.
I think it includes 10.
What confused me with their question was it said most 10.

So I wrote r less or equal to 10 you think?
Ok I I got it it's a closed circle < = 10. Thank you Bob.
