Answer:
x> 30
Step-by-step explanation:
+ First, is the inequation 3x - 52 > 28.
+ If Yes, so we can solve:
3x - 52 > 28
3x - 52 + 52 > 28 +52
3x > 90
3x/3 > 90/3 (divide both sides by 3>0)
x > 30
Answer:
Yes, the 2011 proportion of neuroinvasive West Nile virus cases is more than the 2010 proportion of neuroinvasive West Nile virus cases.
Step-by-step explanation:
2010 proportion:
629 cases out of 1021. So the proportion is:
2011 proportion:
486 cases out of 712. So the proportion is:
0.683 > 0.616 so the 2011 proportion of neuroinvasive West Nile virus cases is more than the 2010 proportion of neuroinvasive West Nile virus cases.
Each oil change ( x ) takes 22 minutes which can be represented as 22x.
Each tire rotation ( y ) takes 18 minutes, can be represented as 18y
Now, we have only 5500 minutes available, therefore the sum of both things can not last more than this time.
The inequality represented is:
2x-y=8...(1)
x+y=7....(2)
from (2)
y=7-x....(3)
put (3) into (1)
2x-(7-x)=8
2x-7+x=8
2x+x=8+7
3x=15
x=5.....(4)
put (4) into (2)
x+y=7
5+y=7
y=7-5
y=2
