Answer:
Step-by-step explanation:
3 (4 -6) = -8 is correct. The next step is to combine 4 and -6, obtaining
3(-2)
and this 3(-2) should equal -6, which is not the same as -8.
3(4 - 6) = 12 - 18, which differs from the student's solution. This is the reason for the wrong answer.
29/29
/ means division so 29/29=1
x = 0.72
Given
3.8x = 2.736 ( divide both sides by 3.8 )
