Answer:
250.50 - 35m = 300 - 45.25m
Step-by-step explanation:
Whenever an equation asks for when it will take x (or m in this case) amount of things or time you should know that there will be 2 different equations that have to equal each other
The equation will be 250.50 - 35m = 300 - 45.25m
The 35m is being subtracted from 250.50 because they are losing money each time they spend. This also applies to 45.25m
Also 35m and 45.25m are variables because it says they spend that much money each month. They don't specify how many months, so we have to put a variable after it.
Answer:
:0 no one knows
Step-by-step explanation:
By Cramer's rule, the solution can be found as the ratio of determinants. The numerator is the matrix with the right-side constants replacing the coefficients of the variable of interest. The denominator is the matrix of coefficients.
![x=\displaystyle\frac{det\left[\begin{array}{cc}-26&-6\\13&2\end{array}\right]}{det\left[\begin{array}{cc}-2&-6\\5&2\end{array}\right]}=\frac{(-26)(2)-(13)(-6)}{(-2)(2)-(5)(-6)}\\\\=\frac{26}{26}=1\\\\y=\frac{det\left[\begin{array}{cc}-2&-26\\5&13\end{array}\right]}{26}=\frac{(-2)(13)-(5)(-26)}{26}\\\\=\frac{104}{26}=4](https://tex.z-dn.net/?f=%20x%3D%5Cdisplaystyle%5Cfrac%7Bdet%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-26%26-6%5C%5C13%262%5Cend%7Barray%7D%5Cright%5D%7D%7Bdet%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%26-6%5C%5C5%262%5Cend%7Barray%7D%5Cright%5D%7D%3D%5Cfrac%7B%28-26%29%282%29-%2813%29%28-6%29%7D%7B%28-2%29%282%29-%285%29%28-6%29%7D%5C%5C%5C%5C%3D%5Cfrac%7B26%7D%7B26%7D%3D1%5C%5C%5C%5Cy%3D%5Cfrac%7Bdet%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%26-26%5C%5C5%2613%5Cend%7Barray%7D%5Cright%5D%7D%7B26%7D%3D%5Cfrac%7B%28-2%29%2813%29-%285%29%28-26%29%7D%7B26%7D%5C%5C%5C%5C%3D%5Cfrac%7B104%7D%7B26%7D%3D4%20)
