Yesterday it took 5 cleaners 4 and 1/2 hours to clean all the rooms in a hotel. There are only 3 cleaners to clean all the rooms
beks73 [17]
If 5 cleaners took 4 hours and 30 min. to clean the whole rooms in a hotel and there's only 3 cleaners, it would take them 6 hours and 30 min. why? because 5 cleaners = 4 hours and 30 min. 4 cleaners = 5 hours ad 30 min. 3 cleaners = 6 hours and 30 min. Anyway so, if they were paid 8.20 for each hour you would multuply that so 8.20x6.5 = ?? and then you divide the answer to 3 and thats your answer

Would you rather discover alien life or an animal that was thought to be extinct?
Vikentia [17]

\boxed{I\; would\; say\; an\; animal\; that\; was\; thought\; to\; be\; extinct.}

<u><em /></u>

The reason i say this is because i don't really want to run into something that i don't know much about. I do know quite a bit about extinct animals more than i do aliens. So, that's my reasoning.

Answer the following equations:
Andrew [12]

Step-by-step explanation:

3(t+5) = 9

3t+15 = 9

3t = -6

t = -2

2(f-7) = -10

2f - 14 = -10

2f = 4

f = 2

-(c - 9) = 4

-c + 9 = 4

-c = -5

c = 5

-6(2t + 8) = -84

-12t - 48 = -84

-12t = -36

12t = 36

t = 3

-10 (s + 2) = -57

-10s - 20 = -57

-10s = -37

s = 3.7

7(3w + 8)/3 = -9

By cross multiplication,

7(3w + 8) = -27

21w + 56 = -27

21w = -83

w = -3.95

35/5 = (F - 32)/9

7 = (F - 32)/9

By cross multiplication,

63 = F - 32

63 + 32 = F

95 = F
