Answer:the cost of renting one movie is $1.5
the cost of renting one video game is $5.2
Step-by-step explanation:
Let x represent the cost of renting one movie.
Let y represent the cost of renting one video game. One month melissa rented 12 movies and 2 video games for a total of $29. This means that
12x + 2y = 29 - - - - - - -1
The next month she rented 3 movies and 5 video games for a total of 32$. This means that
3x + 5y = 32 - - - - - - - - 2
Multiplying equation 1 by 5 and equation 2 by 2, it becomes
60x + 10y = 145
6x + 10y = 64
Subtracting,
54x = 81
x = 81/54 = 1.5
Substituting x = 1.5 into equation 2, it becomes
3x + 5y = 32
3×2 + 5y = 32
5y = 32 - 6 = 26
y = 26/5 = 5.2
2100 divided by 10.50 = 200 hours
200 hours divided by 8 hour days = 25 days
Square both sides
i = sqrt(-1)
i^2 = [ sqrt(-1) ]^2
i^2 = -1
Now multiply both sides by i
i^2 = -1
i*i^2 = i(-1)
i^3 = -i
Final Answer: -i
(this is negative i)
Question says that a bookkeeper is posting to the accounts of a manufacturer of coffee. Their accounting software deals with weights in kilograms, but the company’s handwritten accounts state that they have produced 21,560 pounds (lbs.) coffee this month.
Now we have to find about what entry in kilograms should they put into their spreadsheet.
Basically they want to convert 21560 pounds into kilogram.
We know that 1 pound = 0.453592 Kilograms
Then 21560 pound = 0.453592*21560 = 9779.44352 Kilogram
Hence final answer is approx 9779.44 Kilogram.
Answer:
Step-by-step explanation:
Must be 16 and 21 because we can see
30 and 70 has 10 as factor
24 and 44 has 2 as factor
12 and 30 has 2 as factor and all those factors are greater than one
