Question

when ednas phone is fully charged, it can operate for up to 18 hours before running out of battery. it has been 6 hours since ednas phone was fully charged. let x represent how many more hours ednas phone can operate without running out of battery. which inequality describes the problem? 6 + x < 18 6 + x ≤ 18 solve the inequality. then, complete the sentence to describe the solution. ednas phone can operate for up to more hours without running out of battery.

Explanation:

Step1: Identify the relationship

The 6 - hour usage plus the remaining usage $x$ should be at most 18 hours. So the inequality is $6 + x\leq18$.

Step2: Solve the inequality

Subtract 6 from both sides: $6+x - 6\leq18 - 6$, which simplifies to $x\leq12$.

Answer:

The correct inequality is $6 + x\leq18$. Edna's phone can operate for up to 12 more hours without running out of battery.
