R=2K which equals 2R=4K
4(R=K+8) or 4R=4K+32
Subtract first equation from second equation.
2R=32 so R=16
Plug into first equation
16=2K so K=8
Now plug both into second equation to check
4R-4K=4(R-K)=4(8)=32 it works
So Roberto is 16 and Katie is 8
(In 4 years R would be 20 and K would be 12 which has a difference of 8)
Answer:
16
Step-by-step explanation:
1 times what equals 16
what =16
2 times what equals 32
what=16
etc....
The answer is 16 because the table shows multiples of 16.
16, 32, 48,64, 80....
Yes you should subtract 2 from the sides
The answer to this question is (9.5)...
There is no option saying 9.5?
