The answers would be 11, if you plug it in it would be 5(11)-7=48
Answer:
![Cost = 284 x](https://tex.z-dn.net/?f=Cost%20%3D%20284%20x)
Step-by-step explanation:
Given
![Old = 6245\ units](https://tex.z-dn.net/?f=Old%20%3D%206245%5C%20units)
![New = 6538\ units](https://tex.z-dn.net/?f=New%20%3D%206538%5C%20units)
Required
The cost of units used
First, calculate the number of units used.
![Units = New - Old](https://tex.z-dn.net/?f=Units%20%3D%20New%20-%20Old)
![Units = 6538 - 6254](https://tex.z-dn.net/?f=Units%20%3D%206538%20-%206254)
![Units = 284](https://tex.z-dn.net/?f=Units%20%3D%20284)
Next, multiply the units used by the cost per units,
Since the cost per unit is not given, we assume that it is x.
So, the total cost is:
![Cost = Units * Cost\ per\ units](https://tex.z-dn.net/?f=Cost%20%3D%20Units%20%2A%20Cost%5C%20per%5C%20units)
![Cost = 284 * x](https://tex.z-dn.net/?f=Cost%20%3D%20284%20%2A%20x)
![Cost = 284 x](https://tex.z-dn.net/?f=Cost%20%3D%20284%20x)
Answer:
3,717,000
Step-by-step explanation:
The calculation of paperback copies is shown below:-
Let us assume hardback copies is x, so paperback copies will be 9x
now the equation is
35,000 + x + 9x = 448,000
10x = 448,000 - 35,000
10x = 413,000
![= \frac{413,000}{10}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B413%2C000%7D%7B10%7D)
= 41,300
Therefore, the paperback copies are
= ![9\times 41,300](https://tex.z-dn.net/?f=9%5Ctimes%2041%2C300)
= 3,717,000
Hence, the paperback copies is 3,717,000

Answer and explanation:
Since x = number of true or false questions correct
And y = number of multiple choice questions correct
And each question for x =2 points
each question for y=3 points
since she then needs a total score of more than 93 to pass, we add up total correct questions and
Inequality equation = 2x +3y >93
