It is 4:12 p.m. Emma's mom will be home from work in 70 minutes, and Emma has gymnastics lessons at 6:00 p.m. How much time will Emma have between the time that her mom gets home from work and the beginning of gymnastics lessons?

We know that her mom will be home in 70 minutes and if its 4:12 then that means that her mom will be home at 5:22 because 70 minutes is 10 minutes more than an hour. If her gymnastics lessons are at 6:00 then she has 38 minutes in-between the time her mom gets home and her gymnastics lesson.

Write an inequality that represents the verbal expression.

All real numbers less than 74.

{x < 74; x ∈ R}

Solution:

Given verbal expression is all real numbers less than 74.

R represents the set of all real numbers.

To write the verbal expression into inequality.

Let us assume that the set of all real numbers which is less than 74 are x.

So, all real numbers less than 74 means x < 74 and

x belongs to real numbers.

Therefore, the inequality is {x < 74; x ∈ R}.
