Answer:
The answer is 8°
Step-by-step explanation:
2x + 62° = 5x + 38°
2x – 2x + 62° – 38° = 5x – 2x + 38° – 38°
24° = 3x
3x = 24°
3x/3 = 24°/3
x = 8°
Thus, The value of x is 8°

the horizontal tangent line mean y'=0
8 - 2x = 0
x = 4

Answer: the school paid $80 for the book.
Step-by-step explanation:
Let x represent the amount that the school paid for the book.
Her school charges a lost book fee equal to 75% of the cost of the book. It means that the amount that the school would charge on a book that cost $x is
75/100 × x = 0.75 × x = 0.75x
Sarah received a notice stating that she owed the school $60 for he lost book. It means that
0.75x = 60
x = 60/0.75
x = $80
