How many times does 5.4 go into 60 if it starts at -18?

Answer:
14
Step-by-step explanation:
starting at -18 you must add 5.4 until you reach 60
-18 + 5.4 = -12.6 once (1)
-12.6 + 5.4 = -7.2 twice (2)
-7.2 + 5.4 = -1.8 thrice (3)
-1.8 + 5.4 = 3.6 fourth (4)
3.6 + 5.4 = 9 fifth (5)
9 + 5.4 = 14.4 sixth (6)
14.4 + 5.4 = 19.8 seventh (7)
19.8 + 5.4 = 25.2 eighth (8)
25.2 + 5.4 = 30.6 ninth (9)
30.6 + 5.4 = 36 tenth (10)
36 + 5.4 = 41.4 eleventh (11)
41.4 + 5.4 = 46.8 twelth (12)
46.8 + 5.4 = 52.2 thirteenth (13)
52.2 + 5.4 = 57.6 fourteenth (14)
since 57.6 + 5.4 is over 60, we need to find the difference in how much we need
57.6 - 60 = -2.4
we need 2.4 so subtract by 5.4
5.4 - 2.4 = 3
therefore we should divide
= 14.444...
which means it goes into 60 (starting at -18) 14.444... repeating times
another way to find the answer is
add 18 + 60
18 + 60 = 78
78/5.4 = 14.444... repeating or 14
hope this helps:)

Step-by-step explanation:
Given that At the pet owner’s meeting, there are 20 people who own dog, and 35people who own cat and 9 people own goldfish. Some people own both catand dog and some people own both gold fish and cat. No dog owners owngoldfish. There are twice as many people who own both goldfish and catthan people who own both dog and cat.
Total no of people =52
The venn diagram attached gives a clear picture
assuming x to be owners of both dog and cat. Then 2x is for both goldfish and cats.
Totalling all mutually exclusive we get
64-3x=52
x=4
No of owners who own both cat and dog =4
