Final answer:
The inequality for the box tops collected is 5000 ≤ x, and the inequality for a car's speed is x ≤ 35, with 'x' representing the number of box tops and the car's speed in kilometers per hour, respectively.
Step-by-step explanation:
For the first part of the question regarding the box tops for a fundraiser, the inequality that would represent the goal of collecting at least 5,000 box tops is 5000 ≤ x where ‘x’ represents the number of box tops collected. This inequality means that the number of box tops collected should be 5,000 or more.
The second part of the question pertains to the speed limit on a city street, which is set at 35 kilometers per hour. The inequality that describes a car's possible speed, without exceeding the limit, is x ≤ 35 where ‘x’ represents the car’s speed in kilometers per hour. This inequality implies that the maximum speed of the cars should not surpass 35 kilometers per hour.
