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?
Answer:
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;
Hence The equation used to find number of hours customer rented the bike is .
Answer:
RS = 19
Step-by-step explanation:
Given a segment joining the midpoints of 2 sides of a triangle then it is half the length of the third side, that is
- 5x + 44 = (18 + 4x) ( multiply both sides by 2 to clear the fraction )
- 10x + 88 = 18 + 4x ( add 10x to both sides )
88 = 18 + 14x ( subtract 18 from both sides )
70 = 14x ( divide both sides by 14 )
5 = x
Then
RS = - 5x + 44 = - 5(5) + 44 = - 25 + 44 = 19
