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
The answer is -6 is less than 3
Answer:
2.75 hours, or 2 hours and 45 minutes
Step-by-step explanation:
Subtract the cost of materials from the bill, 134-46=88.
Then, for every hour, he charges 32, so divide the difference by 32, 88/32.
Answer:9x
Step-by-step explanation: -9x + 9x = 0
If they add together to give zero then that is the additive inverse. So just change the sign
Answer:
The equation for height is given as
S= -16t2 +V 0 t
Also given
V0 = 128 ft/s
Substituting 192 = -16t2 +128t
Which is simplified as
t2 -8t +12 =0
Which gives t = -2 sec and t= 6 sec ( -2 can be ignored)
Using S = -16 *6*6 +128 *6 = 192 ft
