Question

Translate the sentence into an inequality.The sum of a number times 10 and 20 is greater than 27.Use the variable b for the unknown number.

Answer 1

Step 1: Let the variable (unknown number) be b

10 times the number is given by

`10* b\Rightarrow10b`

Step 2: The sum of the 10 times the number and 20 can be expressed mathematically as

`10b+20`

Step 3: The symbol for the inequality "greater than" is given by

`>`

Step 4: The sum of a number times 10 and 20 is greater than 27 is written as

`10b+20>27`

Hence, the sum of a number times 10 and 20 is greater than 27 is translated into an inequality as

`10b+20>27`
