Answer:
13
Step-by-step explanation:
the product of 3 and a number
that means 3*something
we can call something "x"
so we have
3*x = 3x
is 39
That means that something is equal to 39
let me write it
something = 39
but we know that this something is 3x
so we have
[tex]3x=39\\\\\frac{1}{3}*3x=\frac{1}{3}*39\\\\x=\frac{39}{3} \\\\x=\frac{3*13}{3} \\\\x=13[/tex]
so the number is 13
