Question

The sum of 4 and c is greater than or equal to 16.

Answer 1

The sum of 4 and c is greater than or equal to 16

the algebraic expression is equal to

$4+c\text{ }\ge16$

solve for c

subtract 4 both sides

$\begin{gathered} 4+c\text{ -4}\ge16-4 \\ c\text{ }\ge12 \end{gathered}$

the solution for c is all real numbers greater than or equal to 12
