Answer:
I want to say its C - 8.12 units. But I think it could also be D- 8.25 units. Just not 100% sure.
Natural numbers or counting numbers
What we know:
1/6 = what Cody wathed
1 stands for the unit that cody has watched a move (minutes)
6 = stands for the entire length of the movie (minutes)
Tharefore: If 6 stands for the entire length of the movie the movie is equal to 3 hours. However we are giving the unit in minutes not in hours, it would be:
3 x 60 = 3 stands for the ours 60 stands for minutes in an hour. That equals to 180.
This means that the 6 = 100% = 180min of the movie.
To figure what 1 stands for we need to divide 1/6. That will equal to 0.1(6). 0.1(6) x 180 (minutes of the entire movie) = 30 which would be the answer. Here is what you should have done using mathematical communication:
converting 3 h to minutes:
3 x 60 = 180 minutes
180 = the length of the entire movie
1/6 = 0.1(6)
0.1(6) x 180 = 30
... 30 /180 is the fraction of minutes that Cody spend watching the movie
in other words Cody just spent 30 min watching the movie.
Answer:
x < -2; x > 5
Step-by-step explanation:
5x + 7 < - 3 3x - 4 > 11
-7 -7 +4 +4
5x < - 10 3x > 15
/ 5 /5 /3 /3
x < -2 x > 5
6-3x=2x
In order to solve these, you first want to get all the variables on one side. So, you add 3x to both sides.
6=x
The answer is x=6
Hope this helps!
