Answer:
r = - 
Step-by-step explanation:
Given that r varies inversely as t , then the equation relating them is
r = 
← k is the constant of variation
To find k use the condition t = - 6 when r = - 2, then
- 2 = 
( multiply both sides by - 6 )
12 = k, thus
r = 
← equation of variation
when t = - 7, then
r = 
= -
Answer:

Step-by-step explanation:
Answer:
9/16 of the students
Step-by-step explanation:
first you can simplify 15/20 to 3/4
you can simplify 12/16 to 3/4
3/4*3/4=9/16
1...2...5...10 are the factors of 20 that go into 50.
ANSWER:
7/8 and 6/8

3/4 multiply the top and bottom by 2 so
3*2=6
4*2=8
so its so 6/8
