Answer:
There are 10 students
Step-by-step explanation:
69.55-(5.35*3)= 53.5
53.5/10=5.35 which is what each ticket costed
So the answer is 10 students
The factored form of this quadratic would be : (2x - 5)(x + 3) you can use the foil method to multiply the binomials to verify.
20+x = 12+2x is the answer and x=8
20 divided by 40=2
20x40=800
800 divided by 40= 20
Dx(xy +y^2 = 1)
Dx(xy) +Dx(y^2) = Dx(1)
(x'y + xy') +(2y y') = (0)
x'y + y'(x +2y) = 0
y'(x +2y) = -x'y
y' = -x'y/(x +2y)
