J+S=24 and J=S+6 represents the relationship between ages.
John is 15 years old and Sally is 9 years old.
Step-by-step explanation:
Let,
John's age = J
Sally's age = S
According to given statement, the sum of their ages is 24;
Eqn 1
John is 6 years older than Sally means we will add 6 in Sally's age;
Eqn 2
Putting value of J from Eqn 2 in Eqn 1;
Dividing both sides by 2
Putting S=9 in Eqn 2
J+S=24 and J=S+6 represents the relationship between ages.
John is 15 years old and Sally is 9 years old.

Answer:
ok so. Your answer is that the population grew by about 3% (1,722,862 people)
Step-by-step explanation:
You would just solve 53,594,378 by 55,317,240. You would get a number right around 96.88 so you would round up to 96.9 or 97. From there, you would subtract 100-97 or 100-96.9 to get 3 or 3.1, that is how you know what percentage something grew or shrank by. :) hope this helps you
Answer:
Step-by-step explanation:
Given lines in parametric form
line 
direction vector of 
Line 
direction vector of 
therefore
thus lines are parallel.
(ii)distance between two lines is
is given by
=s
=3s
where 
=3
=-2
=-3
=-9
=6
=9
distance(d)=0 units since value of the matrix
is zero
