Answer:
1. Distributive property
2. Combine like terms
3. Addition property of equality
4. Division property of equality
Step-by-step explanation:
7x - ½ ( 8x+ 2 ) = 6 Distribute the -½
7x - 4x - 1 = 6 Combine like terms
3x - 1 = 6 Add 1 on both sides
3x = 7 Divide 3 on both sides
x = 7/3

Answer: The distance from the campsite to the foot of the mountain is 2310 ft (approx)
Step-by-step explanation: We have been given that the scout on the mountain top has spotted a campsite and he did so while looking down from a 33° angle of depression. If we label his position as point A, the foot of the mountain as point B and the campsite as point C, then it means the scout has formed an angle of 57° between point A and point B. Now we have a right angled triangle ABC with angle A measuring 57°
Using the trigonometrical ratio of tangent
Tan A = opposite/adjacent
Tan 57 = BC/1500
1.5399 = BC/1500
When you cross multiply both sides you have
1.5399 × 1500 = BC
2309.85 = BC
Approximated to the nearest foot,
BC = 2,310 ft
