Answer:

\frac{11x}{3y}

Step-by-step explanation:

Make both a single fraction by adding together.

\frac{3(7x) + 1(12x)}{9y}

NeX [460]

Options were not present in the question we are Stating below;

Rashida owns a bike rental company. She charges an initial fee of $10 for each rental and an hourly rate of $4. A customer paid $34 for a bike rental. Which of the equations below could be used to find how many hours, x, the customer rented the bike?

34 = 10 - 4x\\\\34 = 4 + 10x\\\\34 = 10 + 4x\\

Answer:

34 = 10 + 4x

Step-by-step explanation:

Given:

Amount customer paid = $34

Initial fee = $10

Hourly rate = $4

We need to write the equation used to find how many hours, x, the customer rented the bike.

Solution:

Let the number of hours customer rented the bike be 'x'.

Now we can say that;

Amount customer paid is equal to sum of Initial fee plus Hourly rate multiplied by number of hours customer rented the bike.

framing in equation form we get;

34 =10+4x

Hence The equation used to find number of hours customer rented the bike is 34 =10+4x.
