If each shirt needs eight buttons you find out what times (×) Eight equals (=) 80
8×10=80
So Eight buttons per shirt
So together they made 10 shirts
but they ask how many Timor made so you do 10 ÷ 2= 5
Timor Made Five (5) Shirts
Then d = e by transitive property
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 =
= - 
580/2=290
the airplane flies 290 per half hour.
