Given:
a.) The price of an item has dropped to $63 today.
b.) Yesterday it was $140.
For us to be able to determine the percentage decrease, we will be using the following formula:
We get,
Original Price = $140
Present Price = $63
Therefore, the decrease of the price in percentage is 55%.
Answer:
A. 4(2y-9)
Step-by-step explanation:
Both terms are divisable by 4 and would bring them to the smallest whole degree
Describe um it’s a line and has a F
Since you can spend all but 20%, then you can spend the rest, namely the 80%.
whatever% of anything is just (whatever/100) * anything.
therefore, 80% of 225 is then (80/100) * 225, that much.
2x + 5y = -8 . . . (1)
-133x - 4y = -8 . . . (2)
(1) * 4 => 8x + 20y = -32 . . . (3)
(2) * -5 => -665x + 20y = 32 . . . (4)
(3) - (4) => 673x = 0
x = 0
From (1), 2(0) + 5y = -8
5y = -8
y = -8/5
