Step-by-step explanation:
im also from k12 lol
6x-21=105
+21. +21
6x=126
×=21
21y=75
Divide 21 from 75
Y= 3.6
x is your starting running time. 1/10 of a minute is 6 seconds, so you can do x - 6(6). 6 times 6 = 36, so your answer is x - 36 seconds. 36 seconds.
14/16
If you multiply 8 by 2 you get 16 so multiply 7 by 2 and you get 14/16
