102/159 = x/4
34/53 = x/4
34(4) = x(53)
136 = 53x
136/53 = x
Amount charged for downloading individual songs = x dollars
Amount charged for downloading an entire album = y dollars
In respect to person A:
6x + 2y = 25.92
3x + y = 12.96
y = 12.96 - 3x
In respect to person B:
4x + 3y = 33.93
Putting the value of y from the first equation in the second, we get
4x + 3(12.96 - 3x) = 33.93
4x + 38.88 - 9x = 33.93
- 5x = - 4.95
x = 0.99 dollars
Putting the value of x in the first equation, we get
y = 12.96 - 3x
= 12.96 - 2.97
= 9.99 dollars
Answer: The answer is: C.
~ i hope this is correct, if not im sorry, have a gr8 day my friend!~
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Im pretty sure that its D because the y intercept is 8 in this equation because when the line intersects on the y axis its on (0,8) and on horizontal and vertical lines the slope is 0. so pretty sure its D
Answer:
The correct answer is option 3.
50.8°
Step-by-step explanation:
Cos ∅ = Adjacent side/Hypotenuse
From the given figure we can see that it is a right angled triangle.
<u>To find the value of x</u>
Cos x = Adjacent side/Hypotenuse
Adjacent side =4.3
Hypotenuse = 6.8
Cos x = 4.3/6.8 = 0.6323
x = cos⁻¹ (0.6323) = 50.77 ≈ 50.8°
Therefore the correct answer is third option.
50.8°
