The age of Blain is 23 years old
<h3><u>Solution:</u></h3>
Let the age of Blain be "a" and age of Jillian be "b"
Given that Blain is two years older than three times Jillians age
So we can frame a equation as:
age of blain = 2 + 3(age of Jillian)
a = 2 + 3b ----- eqn 1
Also given that Jillian is also 16 years younger than Blain
Age of Jillain = Age of Blain - 16
b = a - 16 ---- eqn 2
Substitute eqn 2 in eqn 1
a = 2 + 3(a - 16)
a = 2 + 3a - 48
a - 3a = -46
-2a = -46
a = 23
Thus the age of Blain is 23 years old
Let,
the numbers be "x" and "y"
According to the question,
x = 4y ......................................................equation (1)

...................................equation (2)
Taking equation (2)

Substituting the value of "x" from equation (1), we get,





Cross multiplying, we get,


<u />



Now,
Taking equation (1)
x = 4y
Substituting the value of "y", we get

So, the numbers are

Answer:
A
Step-by-step explanation:
The base is the circle.
To find the area of the circle, use pi*r^2
pi = 3.14
r = 6
- Area = 3.14 * 6^2
- Area = 3.14 * 36
- Area = 113.04
