Answer:
B
Step-by-step explanation:
the opposite angles of the quadrilateral ABDC are supplementary , that is
∠ BDC + 40° = 180° ( subtract 40° from both sides )
∠ BDC = 140°
Not drake!
m=number of members
n=number of nonmembers
n+m=25
cost=550=20m+25n
simplify by dividing by 5
110=4m+5n
so we have
n+m=25 and
5n+4m=110
multiply first eequation by -4 and add to second equation
-4n-4m=-100
<u>5n+4m=110+</u>
n+0m=10
n=10
subsitute
n+m=25
10+m=25
m=15
15 members
10 non-members
