The force of attraction , f of a body varies directly as its mass m and inversely as the square of the distance d from the body. when m=8 kilograms and d=5 meters , f =100 newtons. find f when m=2 kilograms and d = 15 meters.

Vvaries directly as d. find the constant of variation in each case.(note: kindly explain how the result turned out that way.)1. v = 7d(i'll only pick the items that include cases that seem quite different from the rest of the cases. it'd be highly appreciated if you do answer each of them.)2. 8d = v3. 12d = 9v4. 5v/9 = d5. v³ = d²/166. 3v = 1/3d9. 2/5v = ½dquestion: what's the difference between "v" and "d"? kindly answer that in a separate comment.each answer that's appropriate to a certain number must be in a separate comment, containing the explanation, of course. thank you for your time.lesson: ! direct linear function! ​

Solving word problem involving system of linear equation.(topic)solve by using a system of two equation in two variables.1. the sum of two numbers is 42. the difference between three times the greater number and 3 times the lesser number is 14. find the two numbers.2. the difference between two number is 21. if twice the smaller number is added to one half the larger number,the result is 38. what are the numbers? pasagot naman po,assignment ko po kasi ito. i hope makuha ko po ang sagot asap​

What will you do make it 3/4 equal to 1? ​
