Question

Write all of the digits that can replace each 3,408< 3,_30< 3,540

Answer 1

The digits that can replace are 5 and 4

Explanation:

Let

x -----> the digit

we have

3,408 < 3,X30 < 3,540

Divide into two inequality

Solve for the first inequality

1) 3,X30 < 3,540

The digits that can replace X are -----> 5,4,3,2,1,0

Solve for the second inequality

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
