Question

Twelve more than a number x is less than three times the number. Which of the following inequalities best represents this information?

a. 12+x>3x

b. x+12<3x

c. 12x<3x

d. x+12>3x

Answer 1

Here is an example:

Eight more than a number x is less than 2 times the number.

8 more is 8 +

your number is x so now you have 8+x (or x+8)

Less than is the < symbol. > is the greater than symbol)

2 times the number is 2x.

8+x < 2x

Also, x+8 < 2x is another way you can write said problem.

Apply this information to your current problem.

Answer 2

Hi Calvin,

"Twelve more than a number x" represents adding 12 to x or: x + 12

"Three times the number" would be written as : 3x

" is less than " would be written as : <

The correct choice is b or x+12<3x
