Question

Translate the sentence into an inequality.Twice the difference of a number and 8 is less than – 23.Use the variable b for the unknown number.

Answer 1

2(b - 8) < -23

Explanation:

To translate the sentence, we ill need to break it down into bits

difference of a number and 8

let the number = b

Difference means subtraction. We will subtract 8 from the number

difference of a number and 8 = b - 8

Twice the difference: we will multiply the difference by 2

Twice the difference of a number and 8 = 2(b - 8)

Twice the difference of a number and 8 is less than – 23

less than – 23 is written as < -23

Twice the difference of a number and 8 is less than – 23:

2(b - 8) < -23
