change the units to yards
21/3 = 7 yds
12/3 = 4 yds
A= 7*4 = 28 yds
cost = 29.56 * 28 = 827.68
the total cost is $827.68
Let s be standard and h be high-quality versions of the song.
To figure this out, let's make a system of equations:
2.5s + 4.5h = 5740
h = 4s
First substitute the second equation into the first for h.
2.5s + 18s =5740
Then combine like terms.
20.5s = 5740
Lastly, divide each side by 20.5 to get the number of standard downloads:
s = 280
Hope this helps!
Answer:
y
Step-by-step explanation:
Just use the formula...,
; y - y(coordinate) = slope × [ x - x(coordinate)]
; where we firstly have to calculate the slope...,
; (8 - 2)/(4 - 6) = -3
Then substitute into the formula using point(4, 8)...and you can also use the other point if you wish to
; y - 8 = (-3)(x - 4)
; y - 8 = -3x + 12
Hence the equation of the line....,
; y = -3x + 20
.006, hope that helps, multiplying or dividing by ten you can just move the decimal point
