Answer:
yes
Step-by-step explanation:
Answer:(10x - 3y) • (100x2 + 30xy + 9y2)
Step-by-step explanation:
(1000 • (x3)) - 33y3
(23•53x3) - 33y3
(10x - 3y) • (100x2 + 30xy + 9y2)
100x2 + 30xy + 9y2
(10x - 3y) • (100x2 + 30xy + 9y2)
Let x represent the price they charge hardcover book and let y represent the price they charge for a paperback book.
4x + 10y = 62 . . . . . (1)
5x + 7y = 61 . . . . . . (2)
(1) x 5 ⇒ 20x + 50y = 310 . . . . (3)
(2) x 4 ⇒ 20x + 28y = 244 . . . . (4)
(3) - (4) ⇒ 22y = 66
y = 66 / 22 = 3
4x + 10(3) = 62
4x = 62 - 30 = 32
x = 32 / 4 = 8
Therefore, the price for a hardcover book is $8 and the price for a paperback book is $3.
