Answer:
John is currently 6 years old.
Step-by-step explanation:
2 years ago: x years
Current time: x+2
In 6 years: x+8
EQUATION:
3(x)=x+8= 3x=x+8
(subract x from both sides)
2x=8
x=4
Therefore, John is 6 years old in current time

The value of n.
x = 48.62
Step-by-step explanation
Perímetro = diámetro/pi
(2x - 3)/pi = 30 pies
2x - 3 = 30 * pi
2x - 3 = 94.25
2x = 94.25 +3
x = 97.2/2
x = 48.6

the answer is 40√3feet per second
v=√16.√300
v= 4. 10√3
NB:10√3=√100 .√3=√100.3= √300
Hence v =40√3ft per second
