Is there information we are missing to this problem? What I believe we are missing is the amount of money she starts off with and the other three items she finds.
Answer:
Step-by-step explanation:
A={1,3,5,7,9,...}
2 * 200 * 300 = 200 + x * 300 + x = (200 + 300) * x
Solve for x.
Answer:
90 minutes
Step-by-step explanation:
In order to calculate a percentage of the minutes of video we simply need to divide the percentage by 100 and then multiply that value by the total number of minutes that the flash drive can hold. Since we are given this total number of minutes then we can simply plug it in and solve for x which represents the percentage of memory used in minutes.
x = 200 * (45 / 100)
x = 200 * 0.45
x = 90 minutes
Therefore, Kenzie has already used 90 minutes of video on the flash drive.
Multiplication property of equality (Multiply both sides by 2)
9(8 - x) + 72 = 204 - 5(3x + 24)
Distributive property
72 - 9x + 72 = 204 - 7.5x - 60
Combine like terms
-9x + 144 = -7.5x + 144
Subtraction property of equality (Subtract both sides by 144)
-9x ≠ 7.5x
No solution
