Simplifying
5(7x + -3) = 230
Reorder the terms:
5(-3 + 7x) = 230
(-3 * 5 + 7x * 5) = 230
(-15 + 35x) = 230
Solving
-15 + 35x = 230
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 35x = 230 + 15
Combine like terms: -15 + 15 = 0
0 + 35x = 230 + 15
35x = 230 + 15
Combine like terms: 230 + 15 = 245
35x = 245
Divide each side by '35'.
x = 7
Simplifying
x = 7

The answer is the positive one
Answer:
Step-by-step explanation:
Let the speed of the roller coaster at the bottom is v.
radius, r = 47 m
Let the mass is m and the force at the bottom is 2.5 times the weight.
F = 2.5 mg
So, the force is
v² = 1.5 gr
v² = 1.5 x 9.8 x 47
v = 26.3 m/s
