There was 375 adult tickets sold.
425 is 50 more than 375.
425+375=800
Substitute 4 for y. Then -3x^2 + 16 = 52.
Solve for x. Subtract 16 from both sides, obtaining -3x^2 = 36.
Divide both sides by -3, obtaining x^2 = -12. This last result makes no sense, as no square of a real number could be negative. Probably this is where you're ":getting a negative answer."
If imaginary answers were allowed, then x = i*√12 = i*2√3 or x = -i*2√3.
x =
Answer:
Option D
Step-by-step explanation:
(10x + 13) + (12 + 9x) + ( 13x + 12) + 55 + 44 = 360
32x + 136 = 360
Subtract 136 from both sides;
32x = 224
Divide both sides by 32;
x = 7
