Answer: 16 double rooms and 10 single rooms were rented.
Step-by-step explanation:
Let x represent the number of double rooms that were rented.
Let y represent the number of single rooms that were rented.
The total number of rooms rented in a day is 26. It means that
x + y = 26
A motel rents double rooms at $34 per day and single rooms at $26 per day. If all the rooms that were rented for one day cost a total of $804, it means that
34x + 26y = 804 - - - - - - - - - - -1
Substituting x = 26 - y into equation 1, it becomes
34(26 - y) + 26y = 804
884 - 34y + 26y = 804
- 34y + 26y = 804 - 884
- 8y = - 80
y = - 80/ - 8 = 10
x = 26 - y = 26 - 10
x = 16

Step-by-step explanation:
Put the numbers in the expression and do the arithmetic.
![c-4x=-\dfrac{7}{15}-4\cdot\dfrac{2}{5}=-\left(\dfrac{7}{15}+\dfrac{8}{5}\right)\\\\=-\left(\dfrac{7}{15}+\dfrac{24}{15}\right)=\boxed{-\dfrac{31}{15}}](https://tex.z-dn.net/?f=c-4x%3D-%5Cdfrac%7B7%7D%7B15%7D-4%5Ccdot%5Cdfrac%7B2%7D%7B5%7D%3D-%5Cleft%28%5Cdfrac%7B7%7D%7B15%7D%2B%5Cdfrac%7B8%7D%7B5%7D%5Cright%29%5C%5C%5C%5C%3D-%5Cleft%28%5Cdfrac%7B7%7D%7B15%7D%2B%5Cdfrac%7B24%7D%7B15%7D%5Cright%29%3D%5Cboxed%7B-%5Cdfrac%7B31%7D%7B15%7D%7D)
