Oceanside Bike Rental shop charges a 14 dollar fixed fee plus 9 dollars an hour for renting a bike.Sara paid 77 dollars to rent
labwork [276]

Answer:

7 hours

Step-by-step explanation:

We have that the value of the review of a bicycle has the following function:

v = 14 + 9 * t

where t is the time in hours

if we know that Aara paid a total of 77, that is v = 77, we can calculate the value of t, replacing:

77 = 14 + 9 * t

solving for t:

t = (77 - 14) / 9

t = 7

that is to say that Sara left the bicycle in a total of 7 hours

<h3>What is an Equation ?</h3>

An equation is defined as the mathematical statement formed when  two algebraic expression are equated by an equal sign.

It is given in the question that

x> 0 and y>0

\rm \sqrt[3]{\dfrac{x^3}{cy^4} }= \dfrac{x}{4y\sqrt[3]{y}}\\\\\\{\dfrac{x^3}{cy^4} = \dfrac{x^3}{64y^3 \times y} \\\\\\\\\\\therefore\; from \;this \\\\c= 64\\

The value of c = 64 makes the equation true.
