Answer:
Step-by-step explanation:
X divided by (3+7)
Note that "Complement" = 90°, and "Supplementary" = 180°
Let the complement angle of 32 be x
x + 32 = 90
Isolate the x. Subtract 32 from both sides
x + 32 (-32) = 90 (-32)
x = 90 - 32
x = 58
D. 58° is your complement.

If the amount of members are y, then the total number of people who attend is x+y=19. In addition 11*y (since it costs 11 dollars per member)+13*x=209. Subtracting x from both sides in the first equation, we get y=19-x. Plugging that into the second equation, we get (19-x)*11+13*x=209. Multiplying it out, we get 201-11x+13x=209. Subtracting 201 from both sides, we get 2x=8 and by dividing both sides by 2 we get x=4
If you round 23.19 to the nearest whole number you get 23 and if you round 13.7 you get 13. 13+23 is 33. The real numbers are 23.19 and 13.7, add them together and you get 36.89. The exact sum is 36.89 (:
