We have that F is proportional to m1. Hence, we have that F=m1*c when we change the first mass. We also have that F=m2*c when we only change the 2nd mass. Since F scales inversely with the square of the distance, we have that

. Combining all of the facts above, we get that F=c*

where c is a constant.
Answer:
-21.5
Step-by-step explanation:
-12-6=-18 minus 3.5=-21.5
Answer:
515
Step-by-step explanation:
If it's a multiple of five and not ten, that would be the units digit must be 5. Hundreds=units. 11-10=1. So the answer is 515
Answer:
C. You would be finding the total distance. You arent finding the rate because there is no division, and we dont know how long it took hime to ride the original 5. The answer is C.
