* will give brianliest*the work of a student to solve the equation 3(3y − 8) = 10 + 3y is shown below:
step 1: 3(3y − 8) = 10 + 3y
step 2: 6y − 5 = 10 + 3y
step 3: 3y − 5 = 10
step 4: 3y = 15
step 5: y = 5
in which step did the student first make an error and what is the correct step?
step 2: 9y − 24 = 10 + 3y
step 2: 6y + 11 = 10 + 4y
step 3: 6y − 8 = 3(6 + y)
step 3: 3(3y − 8) = 7 + y

Which is the completely factored from of xy^3-x^3y

Boris needs to buy plastic spoons. brand a has a box 42 spoons for $2.37. brand b has a box of 72 spoons for $3.57. find the unit price for each brand. then state which brand is the better buy based on the unit price. round your answer to the nearest cent.

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.
