B, $14.00
Explanation: 49/3.5 = 14.00 which equals x
If you would like to solve the equation x/3 = x/2 - 2 for x, you can do this using the following steps:
<span>x/3 = x/2 - 2 /*6
</span>2x = 3x - 2 * 6
2x = 3x - 12
2x - 3x = -12
-x = -12
x = 12
The correct result would be x = 12.
s = number of standard downloads
2s = number of high-quality downloads
2.8s + 4.6(2s) = 2760
2.8s + 9.2s = 2760
12s = 2760
s = 230
The standard version was downloaded 230 times and the high-quality version was downloaded 460 times.
Refrection of a function in the x-axis give the negative of that function.
Refrection of f(x) = 3x + 2 in the x-axis gives -f(x) = -(3x + 2) = -3x - 2
Therefore, g(x) = -3x - 2
Answer:
7/40
Step-by-step explanation:
7 balls are green-->numerator
7 balls out of 40( in total) are green.
7/40
This means that out of every 40 balls picked, 7 of them should be green.
