Answer:
Closed boundary point
Step-by-step explanation:
It says greater than OR equal too and having a closed boundary will indicate that 21 is apart of the inequality also.
I hope this helps
Answer:
x=18
Step-by-step explanation:
set up the equation:
DBC+DBC=ABC
79+79=(9x-4)
Simplify both sides of the equation.
79+79=9x−4
79+79=9x+−4
(79+79)=9x−4(Combine Like Terms)
158=9x−4
158=9x−4
Flip the equation.
9x−4=158
Add 4 to both sides.
9x−4+4=158+4
9x=162
Divide both sides by 9.
9x
/9 = 162
/9
x=18
Sum of 5 numbers = 39*5 = 195
largest two numbers sum = 49*2 = 98
median = 40
sum of smallest two numbers = 195-(98+40) = 195-138 = 57
45 because 1-4 round down and 6-9 round up to make the 44 become a 50
