The first thing we must do for this case is to define a variable.
We have then:
x: weight of each pallet with cement
We then have the following equation:
16x = 4856
Clearing x we have:
x = (4856) / (16)
x = 303.5 punds
Answer:
each pallet with cement weigh:
x = 303.5 punds
If 19 out of 28 renters keep a pet, there are
renters who don't keep a pet.
Whenever you have a subset of some set, and you want to know which percentage of the set the subset represents, you simply have to compute

So, in your case, you're wondering what percentage of 28 does 9 represent. So, the formula becomes

Answer:




Step-by-step explanation:
<h3>Given information</h3>


<h3>Question 15. f(g(2))</h3>
<u>Substitute values into the first function</u>



<u>Substitute the values of the first function into the second</u>

<u>Substitute values into the first function</u>


<u />
<u>Substitute the values of the first function into the second</u>




<h3>Question 17. g(f(-5))</h3>
<u>Substitute values into the first function</u>


<u>Substitute the values of the first function into the second</u>




<h3>Question 18. f(g(-5))</h3>
<u>Substitute values into the first function</u>



<u>Substitute the values of the first function into the second</u>

Step-by-step explanation:
Rewrite the equation system as:



Now, write the system in its augmented matrix form:
![\left[\begin{array}{cccc}6&8&0&-75\\-3&6&6&5\\2&-9&0&39\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D6%268%260%26-75%5C%5C-3%266%266%265%5C%5C2%26-9%260%2639%5Cend%7Barray%7D%5Cright%5D)
applying row reduction process to its associated augmented matrix:
Swap R1 and R3, and then Swap R1 and R2:
![\left[\begin{array}{cccc}-3&6&6&5\\2&-9&0&39\\6&8&0&-75\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D-3%266%266%265%5C%5C2%26-9%260%2639%5C%5C6%268%260%26-75%5Cend%7Barray%7D%5Cright%5D)

Now we have a simplified system:


From (3):
(4)
Replacing (4) in (2)
(5)
Finally replacing (5) and (4) in (1)

Answer:
1 - 3 (1 quarter is 25 and a dime is 10, so, 3.)
4 - 10
6 - 15
14 - 33
