A number is at most fifteen

x ≤ 15

Step-by-step explanation:

This is a problem about inequality.

These are the inequality symbols:

>            greater than

<            less than

≥            greater than or equal to

≤            less than or equal to

Choose a variable for the number

let "x" be the number

"x" is maximum 15. This means "x" can be 15, 142, 1, 0, -1 etc...

"x" cannot be 16, 17... any number greater than 15.

"x" is less than or equal to 15.

x ≤ 15

You might also see the answer like this:

15 ≥ x

It means the same thing because the "open" side is still facing "15". The "closed" side is still facing "x".

Although, the variable on the left side is standard formatting.

i got 86 for this

hope this !

if you need an explanation just ask

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
