Answer:
The digits that can replace are 5 and 4
Step-by-step explanation:
Let
x -----> the digit
we have
3,408 < 3,X30 < 3,540
Divide into two inequality
<em>Solve for the first inequality</em>
1) 3,X30 < 3,540
The digits that can replace X are -----> 5,4,3,2,1,0
<em>Solve for the second inequality</em>
2) 3,408 < 3,X30
The digits that can replace X are -----> 9,8,7,6,5,4
The solution are all values of X common in both inequalities
therefore
The digits that can replace are 5 and 4
