Answer: 4 hours and 24 minutes
Step-by-step explanation:
Answer: your answer is 36.3 cause it's half of 72.6.
Step-by-step explanation:
12+6x was subtracted from the left but only 12 was subtracted from the right.
6x and 6 are not equal unless x=1
X=-11/15
Each question is worth 4 points (100/25=4)
Therefore, when you divide 83 by 4, you get 20.75, as as he's aiming to get a B, this needs to be rounded up to 21.
Xio would need to get 21 questions right to get a B, hope this helps :)
