Answer:
B
Step-by-step explanation:
if we divide both sides of 6x + 9 = 12 by 3
(6x + 9)/3 = 12/3
2x + 3 = 4 ---> which matches choice B
Answer:
The scale factor of all radii of circle Y to all radii of circle Z is 2.5
Step-by-step explanation:
we know that
The radius of circle Y is 4 units
The radius of circle Z is 10 units
To find the scale factor of all radii of circle Y to all radii of circle Z, divide the radius of circle Z by the radius of circle Y
10/4=2.5
ANSWER
the area of the trim around the glass in the window is option ( D)
i.e (x²+7x+3)
REASON
As given in the question
A window frame has a length of (5x+3) inches an a width of (x+6) inches.
As the shape of the window in the form of rectangle.
Formula
Area of the rectangle = length × breadth
put the value in the above equation
we get
Area of window = (5x+3)× ( x + 6)
= 5x² + 33x + 18 inches²
As given in the question
The area of the glass in the window is (4x²+26x+15) square inches.
Area trim around the glass in the window = area of the window - area of the glass.
put the value
we get
= ( 5x² + 33x + 18 ) - ( 4x²+26x+15)
= 1x²+ 7x + 3 inches²
therefore the correct option is (D)
Hence proved
9 + 0.5n = 35
0.5n = 35 - 9
0.5n = 26
n = 26 : 0.5
<u><em>n = 52</em></u>
The answer is $6.80.
The full price: $8.00 (100%)
The discount: 15%
The discounted price: x (100% - 15% = 85%)
Make a proportion.
$8.00 : 100% = x : 85%
x = $8.00 * 85% : 100% = $6.80
