Answer:
Ashley read 27 books and her brother read 6 books.
Step-by-step explanation:
Let the number of books her brother read be x.
No. of books her brother reads = x
No. of books Ashley reads = 4x + 3
No. of books her brother reads + No. of books Ashley reads = 33
x + 4x + 3 = 33
Evaluate.
5x + 3 = 33
Isolate 5x.
5x = 33-3
= 30
Find x.
x = 30 ÷ 5
x = 6
Amount of books her brother reads = 6
Amount of books Ashley reads = 4(6) + 3
= 24 + 3
= 27

Answer:
–9(3x³ – 8x + 9)
Step-by-step explanation:
–27x³ + 72x – 81
The above equation can be factorised as follow:
–27x³ = –3 * 3 * 3 * x * x * x
72x = 2 * 2 * 2 * 3 * 3 * x
–81 = –3 * 3 * 3 * 3
Common factor = 3 * 3
Greatest common factor = 9
Thus,
–27x³ + 72x – 81 = 9(–3x³ + 8x – 9)
–27x³ + 72x – 81 = –9(3x³ – 8x + 9)
Answer:
$24.5
