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

Find the center and the radius of the circle with the equation: x^2-2x+y^2+4y+1=0?

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality

Can someone show me step by step how to do this?
