Answer:
74
Step-by-step explanation:
You just have to substitute r with 5.
Now, the equation looks like this:
![15(5)-1](https://tex.z-dn.net/?f=15%285%29-1)
Next, solve
first according to PEMDAS
And
equals 75
![\frac{\left[\begin{array}{ccc}1&5\\5\\\end{array}\right] }{75}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%265%5C%5C5%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%7D%7B75%7D)
Lastly, do
which equals 74
![\frac{\left[\begin{array}{ccc}7&5\\-1\\\end{array}\right] }{74}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D7%265%5C%5C-1%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%7D%7B74%7D)
Therefore, 74 is your answer.

Answer:
6Y
Step-by-step explanation:
We need to solve the statement ' Thrice the product of two and "Y" '.
Thrice means 3 times and product means multiply. It means we have to multiply 3,2 and Y.
Let the result is R. It can be calculated as follows :
![R=3\times 2\times Y](https://tex.z-dn.net/?f=R%3D3%5Ctimes%202%5Ctimes%20Y)
We know that, 3×2 = 6
So,
![R=6Y](https://tex.z-dn.net/?f=R%3D6Y)
Hence, Thrice the product of two and "Y" is 6Y.
