Answer:
-7
Step-by-step explanation:
-7 is a solution of the inequality t<-6
By the way, for the number -6, you can think about a temperature below zero. When it is freezing 6 degrees below zero (-6) it is pretty cold.
The question is which number(s) can you substitute for t so that the formula (the inequality) is True.
So let's try for each given value and substitute it for t in t<-6
if you substitute 7 for t you get this:
Is 7 smaller then -6 ?
No that is not true because 7 is bigger then -6.
if you substitute 7 for t you get this:
Is 7 smaller then -6 ?
No that is not true because 7 is much bigger then -6.
if you substitute 6 for t you get this:
Is 6 smaller then -6 ?
No that is not true because 6 is much bigger then -6.
if you substitute -6 for t you get this:
Is -6 smaller then -6 ?
No, that is NOT true because -6 is exactly the same as -6 but NOT smaller then -6...
if you substitute-7 for t you get this:
Please think about temperatures below zero again.
Is -7 colder the -6 ? If so, then the statement is true...
Is -7 smaller then -6 ?
Yes that is true!
So -7 is a solution of the inequality t<-6
