Answer:
[tex]12\leq n-7[/tex]
Step-by-step explanation:
To solve this problem, we need to express the statement as a math expression.
"At most" expresses a maximum value which can be written using the relation [tex]\leq[/tex], which represents a restriction for maximum values.
"A number" refers to a general value that could be express as a variable [tex]n[/tex].
"decreased by" indicates a difference or subtraction.
Having present all this, we can write the expression as
[tex]12\leq n-7[/tex]
In words, TWELVE is AT MOST a NUMBER DECREASED BY 7.
