Alvin's age is two times Elga's age. The sum of their ages is 57. What is Elga's age?

Elga is 19 and Alvin is 38

Step-by-step explanation:

So The first step is to find out Elgas age. You know that Alvin is 2 two times the age of Elga so you need to Divide 57 by 3. (You divide by three because Alvin is 2 times the age of Elga plus the one part that is Elgas.) The product of 57 divided by 3 is 19. So 19 is the age of Elga. now you multiply 19 by 2 and then you get 38 so 38 is Alvins age. And when you add 38 and 19 you get 57

found it xd it ok yt

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
