Answer:
n > -2 or n < -3
Step-by-step explanation:
|2n+5| > 1
We have two solutions one positive and one negative. Remember to flip the inequality symbol for the negative
2n+5 > 1 or 2n+5 < -1
Subtract 5 from each side
2n+5-5 > 1-5 2n+5 -5 < -1 -5
2n >-4 2n < -6
Divide by 2
2n/2 > -4/2 2n/2 < -6/2
n > -2 or n < -3

Answer:
- story 1- B and story 2-A
- x and y is the amount of flyers she gave to each volunteer.
- 3x+12=90 3y+36=90
- x= 26 y=18
3x+12=90
3x+12-12=90-12
3x=78
3x/3=78/3
x=26
3y+36=90
3y+36-36=90-36
3y=54
3y/3=54/3
y=18
I hope this is good enough:
