They do not mean the same thing:
4 in 4000 stands for 4 thousands
4 in 400 stands for 4 hundreds.
You can see, that first '4' means 4 000, while the second one means 400, so the first one is 10 times greater.
6 1/3 is 19/3
8 1/2 is 17/2
4 3/5 is 23/5
Pls mark brainiest
We don't know what ( 5 2 , 7 2 ) is supposed to represent, but it seems unlikely that the sum of those numbers is -6. Hence that is not a solution to the system.
The sum of -4 and 10 is +6, not -6, so that point is not a solution, either.
Neither offering is a solution to the equations.
