Let price of one scarf be $x
Price of the other is 3 more than $x
Therefore price of the other scarf =$x +3
The total price she paid = $25.00
That is, x+x+3=25
2x+3=25
2x=25-3
2x=22
x=22/2
x=11
The price of one scarf is $11 and the price of the other is 11+3=$14
The price of the expensive scarf =$14.
99.69/100=.9969
.9969*20=19.938
Ramon would receive ~ $19.94
Answer:
x = - 2, x = 0
Step-by-step explanation:
- 3x² - 6x ← factor out - 3x from each term
= - 3x(x + 2)
To solve equate to zero
- 3x(x + 2) = 0
Equate each factor to zero and solve for x
- 3x = 0 ⇒ x = 0
x + 2 = 0 ⇒ x = - 2
The object should be placed 20/cm from the lens so as to form its real image on the screen
<h3>Mirror equation</h3>
The mirror equation is given according to the expression below;
1/f = 1/u + 1/v
where
f is the focal length
u is the object distance
v is the image distance
Given the following parameters
f = 5cm
v = 20cm
Required
object distance u
Substitute
1/5 = 1/u +1/20
1/u = 1/5-1/20
1/u = 3/20
u = 20/3 cm
Hence the object should be placed 20/cm from the lens so as to form its real image on the screen

The systems will intersect at (1,-4), and i think the system has infinite solutions (not sure)
