A building code allows a maximum of 140 people in a meeting room. There is one large table in the room, along with some small tables. When filled, the large table seats 15 people, and the small tables each seat 5 people. Which of the following can be used to find t, the greatest number of small tables that can be filled when the large table is also filled? A. 5t + 15 ≥ 140
B. 5t + 15 ≤ 140
C. 15t + 5 ≥ 140

B

Step-by-step explanation:

Because the number of tables have to be less then 140 and you have to multiply to find the number of small tables that can fit

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.
