Larry is 8 years older than his sister. in 3 years, he will be twice as old as she is now. how old are they now?

Let Sister's age now = s  

So Larry is now s + 8  

In THREE Years Sister = s + 3  

Larry = {s + 8} + 3  

But We are told that he will be TWICE as old as Sister is NOW!!!  

So s + 11 = {2s}  

Solve s = 11  

So Sister is ELEVEN Years old and Larry is NINETEEN Years old.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

where's the diagram?
