Answer:
Step-by-step explanation:
Let x represent the number of videos viewed using either plan A or plan B.
Let y represent the cost of viewing x videos using plan A.
Let z represent the cost of viewing x videos using plan B.
Plan A: $3 per video viewed, plus a flat rate of $8 per month. This means that the cost of viewing x videos would be
y = 3x + 8
Plan B: $5 per video viewed and no additional flat rate. This means that the cost of viewing x videos would be
z = 5x
The inequality to determine when the cost of viewing n videos using Plan A is less than the cost of viewing n videos using Plan B would be
3x + 8 < 5x
8 < 5x - 3x
8< 2x
4 < x
x > 4
5.4 because you set up a proportion 7/19=2/x, 19*2=38, 38/7=5.4285, rounded you get 5.4
Answer: The answer is 6.
Step-by-step explanation: The formula for a cube's volume is a^3. Hence, you take the square root of 216, which is 6.
