Celeste and Dora both offer guitar lessons. Celeste charges an initial fee of $5.00, and an hourly rate of $7.25. Dora has an initial fee of $10.25, and an hourly rate of $6.50. At how many hours of instruction will the cost for each instructor be the same? Which equation represents the scenario?
(7.25h + 5) + (6.5h + 10.25)
(5h + 7.25) + (10.25h + 6.5)
5h + 7.25 = 10.25h + 6.5
7.25h + 5 = 6.5h + 10.25

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
