110 students go on a school trip. Each student needs a bottle of water. How many packs are needed?

9 packs

Step-by-step explanation:

Let's assume that a single package contains 12 pieces of bottle water.

so divide the number of total students which is 110 to 12 then you will get 9.16 and round it off to 9. Hope it helps

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

answer: 12   they all have at least 28 days
