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 =
= - 
111 yards
Explanation
Step 1
to solve this we need to know the equivalence

Now, we can apply a rule of three
let x represents the number of yards in 333 ft, so
so

as the ratio is the same, we have a proportion

Step 2
now, solve for x

so, the answer is 111 yards
I hope this helps you

Your welcome. Have a great day :D
If the x-intercept is 7, then the coordinate is 7 along the x-axis and 0 up the y-axis, so the coordinate is (7,0). We now have the two points (4,2) and (7,0).
You can find out the slope of any line using the general equation:

(0-2)/(7-4) = -2/3
The slope of the line is -2/3x.
Answer:
2 hours
Step-by-step explanation:
2 times 35 = 70
70 + 75 = 145
