Answer:
Sally ends at 3 feet below zero point.
Step-by-step explanation:
Let be
the height with respect to zero point, which is represented by the following sum:

Where:
- i-th travelled height, measured in feet.
In addition, positive sign means ascension, whereas negative sign means descent.
The statement can be translated into the following mathematical identity:



Sally ends at 3 feet below zero point.
Consider this explanation:
1) for radius (r):
S=πr², where S - area, r - radius. ⇒ r=√(S/π)=√400=20 ft.;
2) for circumference (L):
L=2πr, where r- radius ⇒ L=2π*20=40π ft.;
3) for the diameter (D):
D=2r, where r - radius, ⇒ D=40 ft..

Answer:
x=4
Step-by-step explanation:
2(8 - 12x) + 8x = -25x + 52
Distribute
16 -24x +8x = -25x +52
Combine like terms
16 - 16x = -25x +52
Add 25x to each side
16 -16x+25x = -25x+52+25x
16+9x = 52
Subtract 16 from each side
16+9x-16 = 52-16
9x = 36
Divide by 9
9x/9 = 36/9
x =4
