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.
Answer:
19
----- = x
40-3a
Step-by-step explanation:
3(ax + 9) = -4 (-2 - 10x)
Distribute
3ax +27 = 8+40x
Subtract 3ax from each side
3ax-3ax +27 = 8+40x-3ax
27 = = 8+40x-3ax
Subtract 8 from each side
27-8 = 8-8+40x-3ax
19 = 40x-3ax
Factor an x on the right side
19 = x(40-3a)
Divide each side by 40-3a
19/(40-3a) = x(40-3a)/(40-3a)
19
----- = x
40-3a
Answer:

Step-by-step explanation:
9/12 x 100% = 75%
There are a total of 12 months so 9 months over 12 months.
Answer:
The car loses $5,635 every year. Multiply 24,500 by 23% (0.23)
<u>The growth factor</u>:
⇒ <em>is the </em><u><em>base in the exponent</em></u><em>:</em>
<em> ⇒ the larger it is ⇒ the greater the growth factor is!</em>
<em />
<u>Let's Analyze our choices:</u>
- c(t)'s growth factor: 5/2
- a(t)'s growth factor: 5/6
- d(t)'s growth factor: 3
- b(t)'s growth factor: 1/50
<u>The greatest growth factor is 3</u>
