Answer:

Step-by-step explanation:

if t varies inversely proportional as r, then,

t ∞ 1/r

t = k.1/r

t = k/r

substitute t =6 and r = 5 into the equation above

6 = k/5

k = 5 x 6 = 30

the equation that represents this variation is given by,

t =30/r

tr = 30

when r =15,

t = 30/15

t =2

What is the midpoint of of VX, find the length of VX
Rashid [163]
The midpoint is exactly in the middle
meaning
VW = WX
3x+7 = x + 25
solve from x
3x + 7 = x + 25
subtract 7 from both sides
3x = x + 18
subtract x from both sides
2x = 18
divide both sides by 2
x = 9 
Now we have x = 9 but we aren't done.

plug what we found into the expressions
3x + 7 
3(9) + 7
27 + 7
34

x + 25
9 + 25
34

34 + 34 
68

The length of VX is 68.
Or option D.) 68

Hope this helps

Please help, il mark brainliest for the right answer
kari74 [83]

Answer:

I think that it may be 33

Because, you see 15-9=6

so you do 20-9=11

Then you do 25-9=16

add them all together to get 33 so i think that's the perimeter

I am really not sure if this is correct...i'm kinda bad at stuff like this
