C. Moved to a different location but congruent in size and shape.
Rigid motion transformations are when a shape is moved, rotated, reflected, or any other type of transformation but the size and shape stay the same.

280 students have a total of 560 points
There 60 more boys(x+60) complete than girls(x)
2*(x+60)+2*x= 560
number of girl =x =110
girl point =110*2= 220
Additive inverses combine to get 0. So, k is -1.4. The sum is 0. Hopefully that will help.
