Feliz [49]
The coach runs 6 miles each day. Because you would do 3 divided by 5, and get 0.6. Then times that by 10 and you get 6.

A motel rents double rooms at $34 per day and single rooms at $26 per day. If 26 rooms were rented one day for a total of $804,
lubasha [3.4K]

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

Solve by Elimination:<br> 8x + 6y = -5<br> 10x + 6y= -13
jonny [76]

Answer:

x= -4 and y= 27/6

Step-by-step explanation:

-(8x + 6y = -5) which converts to -8x -6y = 5

10x + 6y = -13

simplify from there

-8x + 10x = 2x ; -6y + 6y = 0 ; 5 - 13 = -8

soo, now you have

2x = -8

x = -4

then, plug in to find y

8(-4) + 6y = -5

-32 + 6y = -5   add 32 on both sides

6y = 27    divide both sides by 6

y= 27/6 or 4.5
