please tell me the steps and answer to it
A hotel rents a double-occupancy room for $20 more than a single-occupance room. One night the hotel made $3,115 renting rooms, the rented out 15 double-occupancy rooms and 26 single-occupancy rooms. How much does it cost to rent a double-occupany room? How much for single-occupany rooms?
The scince question is this we are learning about levers:
on my way home from schools i got a flat tire. I was about to put on the spare tire when i remembered i took the jack out to make room for mountain bikes. at this time my friend unexpectedly peddled up and asked if i need help. i explained that i didn't have a jack and therefore i couldn't life the car to put the spare on. just as i was about to call AAA, my friend pointed out some long tree branches along the side of the road. %26quot;Would those branches make a lever with enough force to life the car?%26quot; he askes. I said, %26quot;they look strong enough but i'm not sure if they're long enough.%26quot;....
If my car weighs 1545kg, the resistance arm is 40cm, and the effort arm is 5 meters, would the student be able to life the car while i change my tire? explain why or why not. back you answer up with calculations.
PLEASE help me with these 2 questions i am really confused by them.
thanks,
tomHow do i solve this math equation and awser this science question?Well, post your attempt at answering them and I can help explain the confusing parts for you.How do i solve this math equation and awser this science question?double is 20 more than single
so if single=x
then double=x+20
so then you can use those equations and the fact that you know 15 doubles and 26 singles is 3115
3115=26x+15(x+20)
3115=26x+15x+300
2815=41x
68.66=x which is the cost of a single
68.66+20=88.66 is then the cost of a double
not sure about the second question..... haven't taken a physics class in a while....How do i solve this math equation and awser this science question?Single occupancy = x $
Double occupancy = (x +20) $
15 ( x + 20) + 26x = 3115
15x + 300 + 26x = 3115
41x = 3115 - 300 = 2815
x = 2815/41 = 68.66 $
Single occupancy = 68.66 $
Double occupancy = 88.66$
Check your answer.
