Answer:
Age of Anna = x years
Age of Jane i.e. Anna's sister = (x-y) years
a, What was the sum of their ages two years ago?
Solution,
Age of Anna two years ago = (x-2) years
Age of Jane two years ago = (x-y-2) years
Sum of their ages = x - 2 + x-y-2 = 2x - y -4
b. What will be the sum of their ages in 3 years?
Solution,
We have,
Present age of Anna = x years
Present age of Jane = (x-y) years
So,
Age of Anna after 3 years = (x+3) years
Age of Jane after 3 years = (x-y+3) years
Therefore,
Sum of their ages in 3 years = (x+3) +(x-y+3) = 2x - y+6
c. How old was Anna when Jane was born?
Solution,
Here,
According to question,
Jane is y years younger than Anna
So, Anna was y years when Jane was born.
[Suppose your age is 10 years and your brothers age is 14 years. You are 4 years younger than your brother. Also, his age was 4 years when you were born.]

Answer:
Step-by-step explanation:
<u> </u>
3.4 or 3.4 repeating (3.4444444444444444444444∞)
and
3.44 rounded to the hundredth
You can always draw a straight line between two points, so 2 points are always collinear.
However, coplanar means that the two points fall within the same plane. If you’re describing two different points from two different planes, they wouldn’t be collinear, but if they were on the same, they would be collinear.
We can conclude from this information that the answer is B.
Hope this helps!
