Solve with quadratic formula or factor square 2x to the 2nd power -x =3
BabaBlast [244]

Answer:

Step-by-step explanation:

2x²-2x=3

2x²-2x -3 = 0

note :

the discriminat of each quadratic equation : ax²+bx+c=0 ....(a ≠ 0) is :

Δ = b² -4ac

1 )  Δ > 0  the equation has two reals solutions : x =  (-b±√Δ)/2a

2 ) Δ = 0 : one solution : x = -b/2a

3 ) Δ < 0 : no reals solutions

***** in this exercice : a = 2   b = -2   c = -3

Δ = (-2)² -4(2)(-3) =28

x =  (2±√28)/6

Visitors to a carnival can buy an unlimited-ride pass for $50 or an entrance-only pass for $20. In one day, 282 passes were sold
Ghella [55]

Answer:

Number of Unlimited passes sold were 168.

Step-by-step explanation:

Let Number of Unlimited passes sold be x

and Number of entrance-only passes sold be y.

Total number of passes sold =282

Hence,

x+y=282 \ \ \ \ equation \ 1

Also

Cost for unlimited-ride pass = $50

Cost for entrance-only pass = $20

Total Money for one day = $10,680

Hence,

\$50x+\$20y=\$10,680\\

Dividing by 10 on both side we get;

5x+2y=1068 \ \ \ \ equation \ 2

Now multiplying equation 1 by 2 we get;

2x+2y=584 \ \ \ \ equation \ 3

Now Subtracting equation 3 from equation 2 we get;

(5x+2y=1068)-(2x+2y=584)\\3x=504\\x=\frac{504}{3}= 168

x= 168

x+y = 282

168+y =282

y=282-168

y= 114

Hence, Number of Unlimited passes sold are 168 and Number of entrance-only pass sold is 114.
