a shuttle bus to willow creek mall has enough seats for 21 people to ride. right now, there are 12 people on the bus. let x represent how many more people can ride on the bus. which inequality describes the problem? 12 + x ≤ 21 12 + x ≥ 21 solve the inequality. then, complete the sentence to describe the solution. up to more people can ride on the bus.
Answer
Explanation:
Step1: Analyze the problem
The bus can hold 21 people in total and currently has 12 people. The number of additional people $x$ plus the current 12 people must be at most 21. So the inequality is $12 + x\leq21$.
Step2: Solve the inequality
Subtract 12 from both sides of $12 + x\leq21$. We get $x\leq21 - 12$, so $x\leq9$.
Answer:
The inequality is $12 + x\leq21$. Up to 9 more people can ride on the bus.
