#2 A bicycle rental company charges a $20 fee plus $5.50 per hour to rent a bicycle. Another bicycle company charges a $15 fee plus $6.50 per hour to rent a
bicycle. For what number of hours is the cost for the rental the same? Write an
equation for this problem.

5.5h+20=6.50h+15

Step-by-step explanation:

considering that the hours need to be equal to each other, we use the same variable and since the cost needs to be the same we set both equations equal to each other. Then we multiply the amount per hour by the variable h and add the overall fee to make the equation 5.5h+20=6.50h+15

a² + b²= c²

24² + 7² = c²

c= 25

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
