Answer: I think it is 10364 or 10248 because when i put it in a calculator I got 8803.4 or 10296
Step-by-step explanation:
First off, let's convert the percentages to decimal format, so our 77% turns to 77/100 or 0.77, and our 55% turns to 55/100 or 0.55 and so on
now, the sum of both salines, must add up to the 77% mixture, let's say is "y"
so, 11 + 4 = y, and whatever the concentration level is, must also sum up to the mixture's concentration of 77%
anyway thus

solve for "x"
To find the cofactor of
![A=\left[\begin{array}{ccc}7&5&3\\-7&4&-1\\-8&2&1\end{array}\right]](https://tex.z-dn.net/?f=A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D7%265%263%5C%5C-7%264%26-1%5C%5C-8%262%261%5Cend%7Barray%7D%5Cright%5D)
We cross out the Row and columns of the respective entries and find the determinant of the remaining
matrix with the alternating signs.
























Therefore in increasing order, we have;

33,155.22 is the correct answer for this
Answer:
Step-by-step explanation:
- Cost of a bottle of water = 10
- Cost of pizza = 60
- Total amount = 120
- Number of water bottles = x
<u>Equation:</u>
- 10x + 60 = 120
- 10x = 120 - 60
- 10x = 60
- x = 60/10
- x = 6
