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
