Kyle got in the elevator on the 7th floor. He rode up 2 floors and then down 5 floors. Which expression represents the floor Kyl

Arte-miy333 [17]

Answer:

7+2-5=f

Step-by-step explanation:

If he starts on the 7 floor, then he is seven above ground, and that would clarify as a positive number. He then goes up 2 floors, which means we would add 2 to the original number. Going down five would mean we would subtract, because he is getting closer to zero, which is ground level. <em>F</em> represents the floor he is on now.

Hope this helps! (Brainliest please!)
