Question

Can someone help me with my practice? I am having trouble with this question.

Answer 1

We are to solve an inequality and give the answer in graph form.

The inequality is:

`6-5+n\ge\text{ 18}`

Let's solve for n in order to be able to answer the question.

we start by trying to isolate n on one side of the inequality symbol. So first combine 6-5 = 1 and re-write the inequality:

`1+n\ge18`
`\begin{gathered} n\ge18-1=17 \\ n\ge17 \end{gathered}`

Now, subtract 1 from both sides, and you get the final answer:

n must be larger than or equal to 17. WHich agrees with the first answer option provided by the problem.
