Answer:
No real solutions.
Step-by-step explanation:
729s^-5 = 729/s^5
729/s^5 = 3^2(1-s) = 9(1-s)
729=9(1-s)(s^5)
(1-s)(s^5)=81
s^5-s^6=81
Because 81 > 0 this means s^6 must be less than s^5. This is never possible as 6 is even so is always positive and is always greater in magnitude than s^5. The only time this isnt the case is when s is a decimal less than 1, but then the difference would be also less than 1 and not 81.
3s + h = $47
7s + 2h= $107
3s + h =$47
3s - 3s + h = $47 -3s
h = $47 - 3s
7s + 2($47 - 3s) = $107
7s + 94 -6s = 107
s + 94 = 107
s +94 -94 = 107- 94
s = 13
3(13) + h = $47
39 + h =$47
39 -39 + h= $47-39
h = 8
Check
7s + 2h= $107
7(13) + 2(8)= $107
91 + 16= 107
107 = 107
She earns $13 per suit sold and $8 per pair of shoes sold.

x=10 in
Answer:
30 minutes to 40 minutes.
Step-by-step explanation:
From the graph attached,
Distance of Sabrina from her home has been given on y-axis and time taken is on x-axis.
Sabrina's walked 2 miles to reach the library in the duration = 30 - 0
= 30 minutes
She stayed at the library from 30 minutes to 40 minutes (Represented by the straight horizontal line).
Then the third segment represents the journey of Sabrina from library to home.
Therefore, Sabrina was at the library between 30 minutes to 40 minutes.
Hope this helps. I think it's right? haha haven't done this in a while.
