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
Dividing both sides by 2
Putting y=3 in Eqn 1
Casey is 18 years old and Ralph is 3 years old.

Answer: 
Step-by-step explanation:
Given a System of linear equations, the solution of the system is the point 
in which the lines intersect, where "x" is the x-coordinate and "y" is the y-coordinate.
Having the following System of equations:
You can use the Elimination method to find the value of "x":
-Multiply the second equation by 3.
- Add the equations.
- Solve for "x".
Then, you get:
Answer: 43 squared units
Explanation:
So the area is the total amount of the inside of the polygon (I’m not good at explaining) and you get your area from using measurements on the sides of the shape for example for a square let’s say the side is 4 and another side is 4 so you multiply that and you get 16 which is the area
So basically since this one is a open polygon you can just count the inside of the poly using the squares
Answer:
24.84
Step-by-step explanation:
12.15 + 3.75 = 15.90
15.90 + 8.94 = 24.84
