I think the answer is he should've added t instead of subtracting t.
Answer:
Length of the trail = 39473.68 ft
Step-by-step explanation:
Let x be the length of the trail.
Given:
Lodge Elevation = 700 ft
Mountain elevation = 8200 ft
Inclination of trail = 11°
We need to find the length of the trail.
Solution:
Total ascent is difference between mountain elevation and lodge elevation.
Length of the trail is the length of the hypotenuse of right angle triangle where the length of the shortest side is the right angle triangle is 7500 ft and opposite angle is 11°.
Using cosine rule.
Therefore, the length of the trail is equal to 39473.68 ft.

Step-by-step explanation:
The value of the shortest length in the quadrilateral is 29.5cm.
<h3>How to calculate the quadrilateral</h3>
Since they're consecutive, it means that the sides follow each other.
This will be:
x + x + 1 + x + 2 + x + 3 = 124
4x + 6 = 124
4x = 124 - 6
4x = 118
x = 118/4
x = 29.5 cm
Therefore, the value of the shortest length is 29.5cm.

Answer:
<u>a) x = 3</u>
<u>b) z = 10</u>
<u>c) p = 2</u>
<u>d) x = 7</u>
<u>e) u = 1</u>
Step-by-step explanation:
a) 2x = 6
Despejamos x dividiendo por 2 a amabos lados de la eacuacion.
(2/2)x = 6/2
<u>x = 3</u>
Si remplazamos x en la ecuación original:
2(3)=6
6 = 6
Queda demostrado.
b) 10 + z = 20
Despejamos z restando 10 en amabos lados de la eacuacion.
10-10+z = 20-10
<u>z = 10</u>
Si remplazamos z en la ecuación original:
10 + 10=20
20 = 20
Queda demostrado.
c) p + 9 = 11
Despejamos p restando 9 en amabos lados de la eacuacion.
p + 9 - 9 = 11-9
<u>p = 2</u>
Si remplazamos p en la ecuación original:
2 + 9 = 11
11 = 11
Queda demostrado.
d) 3x + 8 = 29
Despejamos x restando 8 en amabos lados de la eacuacion y luego divideindo por 3 en ambos lados de la ecuación.
3x+8-8 = 29-8
3x = 21
(3/3)x = 21/3
<u>x = 7</u>
Si remplazamos x en la ecuación original:
3(7) + 8 = 29
21 + 8 = 29
29 = 29
Queda demostrado
e) 2u + 8 = 10
Despejamos u restando 8 en amabos lados de la eacuacion y luego divideindo por 2 en ambos lados de la ecuación.
2u+8-8 = 10-8
2x = 2
(2/2)x = 2/2
<u>x = 1</u>
Si remplazamos x en la ecuación original:
2(1) + 8 = 10
2 + 8 = 10
10 = 10
Queda demostrado
