They're easy to think about-- oh, it's a little bit more than 8. So 8 and 1/3 is equal to-- the denominator's going to be 3. So this thing over here is the same thing as 25 over 3. So it's 2/3 is greater than negative 4y minus 25 over 3.

Now, the next thing I want to do, just because dealing with fractions are a bit of a pain, is multiply both sides of this inequality by some quantity that'll eliminate the fractions.

Once the inequality is written, you can solve the inequality using the skills you learned in our past lessons.

I've tried to provide you with examples that could pertain to your life and come in handy one day.

Are you ready to dive into the "real world" of inequalities?

I know that solving word problems in Algebra is probably not your favorite, but there's no point in learning the skill if you don't apply it. Pay close attention to the key words given below, as this will help you to write the inequality.Now another way we could have written that is that 768 needs to be less than s. Write an inequality to represent all of the possible temperatures, t, of an undercooked steak. Simone is going snowboarding tomorrow if the temperature is equal to or colder than five degrees celsius.Well, to be an undercooked steak your temperature is going to be less than 135 degrees. You could either just use the less than on your keyboard, or you could click over here on less than. We're assuming your temperature is in Fahrenheit degrees. Write an inequality to represent the temperatures at which Simone will go snowboarding.So our speed has to be greater than the speed of sound. To cook a steak to medium-rare, it needs to have an internal temperature of 135 degrees Fahrenheit.Our speed has to be greater than the speed of sound, which is 768 miles per hour, so s has to be set greater than 768. In either case, our speed is going to be greater than 768 miles per hour. A lower internal temperature will undercook the steak.So y is greater than negative 9/4, or negative 9/4 is less than y.And if you wanted to write that-- just let me write this-- our answer is y is greater than negative 9/4.If you're seeing this message, it means we're having trouble loading external resources on our website.If you're behind a web filter, please make sure that the domains *.and *.are unblocked.When an object travels faster than the speed of sound, it creates a sonic boom.And there's actually a whole video on how sonic booms are created, on Khan Academy.
