and this is my last question
OpenStudy (anonymous):
Rachelle is on the 10th floor of an office building. She climbs up 4 flights of stairs, and later takes the stairs down n flights. Write an expression to show what floor she is on.
10 − 4 + n
10 + 4 − n
10 − (n + 4)
10 + (−4n)
OpenStudy (skullpatrol):
What do think?
OpenStudy (anonymous):
Im not sure about this one kinda hard
OpenStudy (skullpatrol):
Since all the answer choices start with the number 10, why not start there?

...what happens to your 14?
OpenStudy (anonymous):
Not sure
OpenStudy (skullpatrol):
If going up adds to your number,
then what must going down do to the number?
OpenStudy (skullpatrol):
10 + 4 = 14
Climb up^ 4 flights of stairs.
OpenStudy (skullpatrol):
Let n = the number of flights of stairs.
