Question

Write the word sentence as an inequality. Then solve the inequality. Eight times a number $n$ is less than 72

Answer 1

8n < 72

n < 9

Explanation:

Note that

> means greater than

< means less than

≥ means greater than or equal to

≤ less than or equal to

for example : 2 < 3 means 2 is less than 3

3 >2 means 3 is greater than 2

8 times n = 8n

8n is less than 72, this can be represented by the equation : 8n < 72

to determine the value of n, divide both sides of the equation by 8

n < 9
