Answer:
A) 420 seconds = 7 minutes
B) 8 times
Step-by-step explanation:
A) After how many second would all three things happen together again?
Solution:
His clock ticked every 5 seconds , a tap was dripping every 7 seconds and his pet dog snored every 12 seconds. It all happens simultaneously = 5*7*12=420 seconds
B) How many times would all three things happen together again between midnight and one o'clock
Since all these events happen together after every 420 sec = 7 mins and there are 60 mins between midnight and 1 o'çlock , thus 60/7 = 8 times ....
Set each set of parentheses to 0 and solve for x.
X—6 = 0
X = 6
X + 5 = 0
X = -5
X-9 = 0
X = 9
The zeros are 6, -5, 9
the answer is x= 8, and y=5
Pretty much, write two problems that equal to 0
Answer:
It is A because if x=1 the y goes more than 1 but is at 1/2 and it would be 3/2
