Practice makes perfect
Every inequality has an inequality symbol and values or expressions on either side of this symbol. In this exercise, we have the phrase less than, so we can identify that the inequality symbol should be <.
Three < the sum of a number s and 4
On the right-hand side, we have one key phrase: the sum of. These words tell us the operations that will be used in our inequality. The sum of indicates addition.
the sum of a number s and 4
s+4
On the left-hand side, we have a constant. Putting these sides together, we have a complete inequality.
Three is less thanthe sum of a number s and 4
3 < s+4
