Joshua paid a mechanic x dollars per hour for a 6-hour job plus $90 for parts. The total charge was $360. Which equation can be used to determine how much the mechanic charged per hour?

6x = 360 + 90

6x = 360 − 90

(90 + 6)x = 360

(90 − 5)x = 360

1. 2. ∠b and ∠y are right angles. 3.? 4.? which two statements are missing in steps 3 and 4? ∠x ≅ ∠c △abc ~ △zyx by the sas similarity theorem. ∠b ≅ ∠y △abc ~ △zyx by the sas similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem.
