Answer:
6) 22,408
7) 8,993
8) 68,701
Step-by-step explanation:
6) 122408 - 100000 = 22,408
7) 8993/999 = 9 2/999
8) 98,700 - 29,999 = 68,701

Answer:
60x
Step-by-step explanation:
Answer: two over three
Step-by-step explanation:
line intercepts y at (0,-2)
Therefore, 
Substitute x = 3 in y =ax-2
To find the x-intercept, y = 0
The slope is 2/3
y-intercept is -2
So two over three
Answer:
It’s 60miles
Step-by-step explanation:
We assume the trip is "d" miles and that the "extra hour" refers to the additional time that a current of 2 mph would add. That is, we assume the reference time is for a current of 0 mph.
The time with no current is ...
time1 = distance/speed
time1 = d/12 . . . . hours
With a current of 2 mph in the opposite direction, the time is ...
time2 = d/(12 -2) = d/10
The second time is 1 hour longer than the first, so we have ...
time2 = 1 + time1
d/10 = 1 + d/12
6d = 60 + 5d . . . . multiply by 60
d = 60 . . . . . . . . . subtract 5d
The one-way distance is 60 miles.
