Look at the word INEQUALITY. It is a bit like the word UNequal.
An inequality is like an equation but instead of both sides being equal they are unequal.
If two things are unequal, then one will be less than the other and one will be more than the other.
You should know the following symbols:
< is less than
> is more than
≤ is less than or equal to
≥ is more than or equal to
If p + 3 ≤ 8, which of the following are possible solutions?
p = 3
p = 8
p = 10
p = -7.5
p + 3 ≤ 8
Subtract 3 from both sides
p ≤ 5
p can be any number less than or including 5.
So the possible answers are p = 3, p = -7.5
