Answer: 102.9 m

Step-by-step explanation:

First, use Pythagorean to find the length of AC

AB² + AD² = AC²

50² + 80² = AC²

2500 + 6400 = AC²

8900 = AC²

94.34 = AC

Next, subtract 15 (the diameter of the circle) from AC to find the length of the straight line.

94.34 - 15 = 79.34

Next, find the circumference of the circle

C = πd

C = 15π

They are only walking around 1/2 of the circle so divide it by 2.

(1/2)C = (15/2)π

≈ 23.56

Add the straight line (79.34) and the half circumference (23.56) to find the total distance traveled.

79.34 + 23.56 = 102.9

For this case we must solve each of the equations proposed:

A) $-6 (2s-1) = 30$

We apply distributive property to the terms within parentheses:

$-12s + 6 = 30$

Subtracting 6 from both sides of the equation we have:

$-12s = 24$

Dividing between -12 on both sides of the equation:

$s = \frac {24} {- 12}s = -2$

B) $-3m = -5 (m-8)$

We apply distributive property to the terms within parentheses:

$-3m = -5m + 40$

We add 5m on both sides of the equation:

$2m = 40$

Dividing between 2 on both sides of the equation:

$m = \frac {40} {2}\\m = 20$

C) $7 (2-g) = 49$

We apply distributive property to the terms within parentheses:

$14-7g = 49$

We subtract 14 from both sides of the equation:

$-7g = 35$

Dividing between -7 on both sides of the equation:

$g = \frac {35} {- 7}\\g = -5$

D) - $7 (3w + 4) = 14$

We apply distributive property to the terms within parentheses:

$-21w-28 = 14$

We add 28 to both sides of the equation:

$-21w = 42$

Dividing between -21 on both sides of the equation:

$w = \frac {42} {- 21}\\w = -2$

Answer:

$s = -2\\m = 20\\g = -5\\w = -2$
