Answer:
I don't know you should have done it when the teacher gave it to you.
Step-by-step explanation:
I just relapsed into self harm and I'm not doing well in this class which already stresses me out enough.
Simplifyiing
the greatest common factor is 3 so
3x - 9y + 12 = 3(x - 3y + 4)
Time out = d/so = d/523
time back = d/sb = d/415
t = time out + time back
11 = d/523 + d/415 find common deneminator
11 = (415d + 523d)/(523*415)
11*523*415 = 415d + 523d
2387495 = 938d
d = 2545 miles
hope this help
No because irrational cant be a simple fraction and 9/15
is 0.6
so... it is not irrational
