Answer:
D
Step-by-step explanation:
($20/hr) is the hourly rental rate, and x is the number of hours for which the bike is rented.
In f(x) = 10 + 20x letting x = 10 results in the total rental cost of the bike for 10 hours (Answer D)
The answer would be 176, because I first combined the x's(minusing 1/4 on both sides), to get 1/4 x +10=54. then I minuses the 10 from both sides to get 1/4x=44. I then multiplied both sides by the reciprocal of 1/4(which is 4) to get x=176

The ideal mechanical advantage of a slope is given by the ratio between the output load, which is simply the weight of the object (), and the input force applied to move the object along the slope:
The energy conservation law states that the potential energy of the object when it reaches the final height h is equal to the work done to move the object along the distance of the slope , i.e.
From this we find
Therefore, we can substitute this into the formula of the ideal mechanical advantage and calculate its value:
