Casey is 18 years old and Ralph is 3 years old.
Step-by-step explanation:
Let,
Age of Casey = x
Age of Ralph = y
According to given statement;
x = 6y Eqn 1
In two years
x+2=4(y+2)
x+2=4y+8
x = 4y+8-2
x = 4y+6 Eqn 2
Putting value of x from Eqn 1 in Eqn 2
![6y=4y+6 \\6y-4y=6\\2y=6](https://tex.z-dn.net/?f=6y%3D4y%2B6%20%5C%5C6y-4y%3D6%5C%5C2y%3D6)
Dividing both sides by 2
![\frac{2y}{2}=\frac{6}{2}\\y=3](https://tex.z-dn.net/?f=%5Cfrac%7B2y%7D%7B2%7D%3D%5Cfrac%7B6%7D%7B2%7D%5C%5Cy%3D3)
Putting y=3 in Eqn 1
![x=6(3)\\x=18](https://tex.z-dn.net/?f=x%3D6%283%29%5C%5Cx%3D18)
Casey is 18 years old and Ralph is 3 years old.

it's B ;)
Step-by-step explanation:
A line segment has two endpoints; that is, it has a starting point and an ending point, much like a dead-end street. Bisector means to divide, not just in two, but in halves, or two equal parts. Therefore, a segment bisector is a point, a line, a ray, or a line segment that bisects another line segment.
The volume of the <span>goldfish pool is V= 0.5ft x 1.5ft x 3ft=2.25 ft^3
so 7.5gallons ----------> 1 ft^3
x=? <----------- </span>2.25 ft^3
<span>x= 2.25 x 7.5 / 1= 16.87 gallons
the answer is </span>16.87 gallons of water <span>
