The incorrect work of a student to solve an equation 2(y + 8) = 4y is shown below:
step 1: 2(y + 8) = 4y
step 2: 2y + 10 = 4y
step 3: 2y = 10
step 4: y = 5
which of the following explains how to correct step 2 and shows the correct value of y?
the equation should be y + 8 = 4y after division by 2; y = 4
the equation should be y + 8 = 4y after division by 2; y = 6
2 should be distributed as 2y + 16; y = 4
2 should be distributed as 2y + 16; y = 8

Isuck at math ; ^; m a student solved this problem and said the answer is 3 feet. chase had a roll of ribbon that contained 7 7/8  feet of ribbon. he cut off one piece that was 3 5/8  feet long and another piece that was 1 1/4  feet from the roll. how much ribbon was left on the roll? is the student's answer reasonable? yes, the answer is reasonable. no, the answer is not reasonable. it should be about 2 feet. no, the answer is not reasonable. it should be about 13 feet. no, the answer is not reasonable. it should be about 4 feet.
