This is exactly like the one with the 'n's that you posted yesterday.
I guess you didn't get enough help on that one to understand it.
<span><u>7k/8 - 3/4 - 5k/16 = 3/8</u>
3/4 is the same as 6/8.
Add it to each side of the equation:
7k/8 - 5k/16 = 9/8
Multiply each side by 16 :
14k - 5k = 18
Add up the 'k's on the left side:
9k = 18
From this point, you can proceed directly to the numerical value of 'k'
if you need it.<u />
In your question, you said you need help, and I showed you how to
strip the problem down so that the only thing left is ' k = something '.
Giving you the answer is no help. Nobody actually needs the answer.

Answer:
4 years difference
Step-by-step explanation:
Answer:
okay, you have pay special attention to time.i.e 60secs = 1 minute, 60 minutes = 1 hour, 24 hours in one day, and 7 days in one week. No. of seconds in one week we are told is 6.1048 x 10 ^5 seconds.
Step-by-step explanation:
s = d/t [ speed = distance/time]
therefor, rearranging, we get d = s x t
Since speed = 2.998*10^5 Km/s and time = 6.048^10^5
d = (2.998 x 10^5) x (6.048 x10^5) = (2.998 x 6.048) x 10 ^(5+5)
d = 18.131904 X 10^10 km
d = approximately 18.132 x 10^10 km (to 3 decimal places)
Supplementary angles sum up to 180°, suppose the supplement of 161° is x. Then
161+x=180
solving for x we subtract 161 from both sides
161-161+x=180-161
x=19
thus the supplement is 19°
