Question

nd the value of $x$ when $x + 30 = 55$.
$x + 30 = 55$
$x = 25$
describe the solution of $x + 30 \geq 55$.
if $x$ is equal to 25, $x + 30$ will be
equal to 55.
if $x$ is greater than 25, $x + 30$ will be
greater than 55.
graph an inequality to represent all possible values of $x$.

Explanation:

Step1: Solve the inequality

$$\begin{align*} x + 30&\geq55\\ x+30 - 30&\geq55 - 30\\ x&\geq25 \end{align*}$$

Step2: Graph the solution

On the number - line, we use a closed circle at \(x = 25\) (because \(x\) can be equal to 25, since the inequality is \(\geq\)) and draw an arrow to the right (because \(x\) can be greater than 25).

Answer:

The solution of the inequality \(x + 30\geq55\) is \(x\geq25\). On the number - line, place a closed circle at \(25\) and draw an arrow to the right.
