Step 1: Let the variable (unknown number) be b
10 times the number is given by
[tex]10\times b\Rightarrow10b[/tex]Step 2: The sum of the 10 times the number and 20 can be expressed mathematically as
[tex]10b+20[/tex]Step 3: The symbol for the inequality "greater than" is given by
[tex]>[/tex]Step 4: The sum of a number times 10 and 20 is greater than 27 is written as
[tex]10b+20>27[/tex]Hence, the sum of a number times 10 and 20 is greater than 27 is translated into an inequality as
[tex]10b+20>27[/tex]
