Answer:
art class / all classes = 16 / (26 + 19 + 21 + 16 + 32) = 16/114 = 8/57Step-by-step explanation:
Answer:

Step-by-step explanation:
We have an extremely large equation and are asked to divide it, so let's solve it step-by-step :
Remove the parenthesis to make it easier to read :

Multiply the numerators :

Multiply the denominators :

Apply the negative rule :

Cancel the common factor which is 18 :

Apply the addition exponent rule :

Subtract :

Apply the rule for y :

Subtract :

Cancel the common factor of z^3 :

If you divide 16 by 2 you get 8, so, 8 teams payed $50, while the other half payed $60.
Hope this helps. ^_^
(If you're gonna add them up it's 8x60=480 + 8x50=400=880) :P
Answer:
For what value of x is f/x 4?
Answer: f (x) = 4 occurs when x = 0 and f (-2) = 2.
Answer:
Step-by-step explanation:
To prove the triangle angle sum theorem,
We will do a construction by drawing a line PQ passing through point F and parallel to line DE.
Statements Reasons
1). ∠PFD + ∠QFD = 180° 1). linear pair postulate
2). ∠QFD = ∠QFE + ∠EFD 2). Angle addition postulate
3). ∠PFD + ∠QFE + ∠EFD = 180° 3). Substitution property
4). ∠PFD ≅ ∠FDE 4). Alternate interior angles
∠QFE ≅ ∠DEF
5). ∠FDE + ∠DEF + ∠EFD = 180° 5). Substitution property
Hence sum of interior angles of ΔDEF is 180°.
