Question

If m varies directly as p, and m = 48 when p = 8, find m when p is 4.

Answer 1

the m = 24 cause if they vary directly and p is halved then m is also halved

Answer 2

cool?

Answer 3

how do i show work for it?

Answer 4

i have another that is the same and i do not understand these types this is the other: if x varies inversely as y^2 and x=6 when y=10, find x when y=2

Answer 5

let m(proportional) tp, where t is any number according to your problem
just find (t) by making m=tp

Answer 6

for example if m=48 then p=8 this shows that t=6

Answer 7

could you draw it out?

Answer 8

write this to show that they r directly perportional, and explain with words that since p=4 is half of p=8 then when p=4 this mean m=48 is halved to get m=24
