Answer:
The first step would be to multiply 2x - 1 by 6, which would be 12x - 6 .

Let the water surface be 0.
He starts at 15 and gets to the water surface of 0 so he travels 15 meters.
He then goes 5 meters below the surface.
15 + 5 = 20 total meters.
The apothem is the distance from which the altitudes of the triangle to one of its sides. It can be calculated through the equation below,
tan 30° = apothem / 0.5(length of side)
Substituting the known values,
tan 30° = 5 / 0.5x
The value of x from the equation above is 17.32. Multiplying this value by 3 (because a triangle has 3 sides), we get an answer of 51.96 cm or approximately equal to 52. Thus, the answer is letter B.
Answer:
54
Step-by-step explanation:
2x+2=3x-52
subtract 2 from both sides
2x=3x-54
x=54
