N a group of 25 Kingswood students: 8 are on the cross-country running team, 13 are on the math league team, and 6 are on both teams. How many of the students are not on a team?

10 Kingswood students are not on a team

Step-by-step explanation:

8-6 is 2 so 13 +2 is 15 so 15 are on a team, 20-15 is 10.

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.
