Answer:
constant proportanality is 12 k=12
Step-by-step explanation:
because 5 time 12= 60 and it keep going and going
Gary gets 4 marbles, because 12/3 is 4. So for the ratio 3:1 to apply, Jo gets 12 marbles and Gary gets 4.
The other angle is 65 degrees
3k+2(5k-3)=7
=>3k+10k-6=7
=>13k=13
=>k=13/13
Therefore, k=1
