Answer:
<em>The man paid $200 for the cow</em>
Step-by-step explanation:
<u>System of Equations</u>
Let's call:
x = price of the cow
y = price of the horse
The man bought the cow and the horse for $500, thus
x + y = 500 [1]
The cow was sold at a profit of 10%, thus:
Sale price of the cow= 1.1x
The horse was sold at a loss of 10%, thus:
Sale price of the horse= 0.9y
The total operation was a 2% loss, i.e. 0.98*500=490. Thus, we have:
1.1x + 0.9y = 490 [2]
From [1]:
y = 500 - x
Substituting in [2]:
1.1x + 0.9(500 - x) = 490
Operating:
1.1x + 450 - 0.9x = 490
0.2x = 490 - 450 = 40
x = 40/0.2
x = 200
The man paid $200 for the cow
Answer:
13
Step-by-step explanation:
Given:
- Square stickers that were 3/4 in long
- The spine is 10 and 1/2 in long
If she laid the stickers side by side without gaps or overlaps so the number of sticker to cover the length of the spine:
10 : 
≈13
She needs 13 stickers cover the length of the spine
E all of these are hexahedra
-4x²+16x-24=-1(4x²-16x+24)=-4(x²-4x+6)
x²-4x+6 has no real roots. ☺☺☺☺
Answer: B. A coordinate plane with points in quadrants II and IV.
Step-by-step explanation:
Let's take the point (-1,1) as an example
The point itself is in the second quadrant
the opposite of the point is (1,-1)
This point is in the fourth quadrant
