Answer:
15 miles
Step-by-step explanation:
Let
be the miles in the circular park path,
the time Louisa takes to finish and
the time Calvin takes to finish both in hours.
Then
, the longitude is equal to the velocity times the time used to finish. So


And the difference between Louisa's time and Calvin' time is 30 minutes, half an hour. So:

Three equations, three unknowns, the system can be solved.
Equalizing the equation with x :

In this last equation replace
with the other equation and solve:
With Louisa's time find x:
Answer:
A) -14 + 2n > 18
Step-by-step explanation:
inequality represents that - 14 more than twice a number is no less than 18.

The answer is 4.9. 32/26=6/x, cross multiple to get 32x=156, divide by 32 to get x=4.875~4.9
21 = 3.7
35 = 5.7
probably the factors have 3.5.7
= 105
let's try :
1 . 105
3 . 35
5 . 21
7 . 15
Yep, correct.
