Answer:
I think Vivek is 20 and his father is 50
Because 30 + 30 equals 60 as he has to be half his age he'll be 30 but that's in 10 years time. you just subtract 30 and 60 by 10 and you'll get 20 and 50
I have no clue what that is
C^2 = 9^2 + 6^2
c^2 = 81 + 36
c^2 = 117
c = √117
c = 10.82
Answer:
See Below
Step-by-step explanation:
Take the the given information and compare to the question being asked
. So insert the x & y's of both equations (ima do y over x to make it easier)

divide 14/4
3.5 = 
then multiply both sides by 40 to isolate y
140 = y
Check by reinserting 140 and divide it by 40
