How do you represent an inequality graphically?

Back

Inequalities are represented on a number line with open or closed circles. A closed circle indicates that the number is included (e.g., >= or <=), while an open circle indicates that it is not included (e.g., > or <).

How do you solve the equation 37 = 12 + x?

Back

To solve for x, subtract 12 from both sides: x = 37 - 12, which gives x = 25.
