Answer:
A & B
Step-by-step explanation:
5x - 2y = 10 (1)
-2.5x + y = -5 (2)
When you multiply (2) by -2, you get (1), so there can be many solutions
To choose from the given options, plug in the values to check which ones satisfy the equation
5x - 2y = 10
A) (2,0)
5(2) - 2(0) = 10
10 = 10 (true statement)
B) (-2,-10)
5(-2) - 2(-10) = 10
-10 + 20 = 10
10 = 10 (true statement)
Account B will cost less because
Account A will cost 0.2*20= $4
Account B will cost
0.1*20 +1.5= 2+1.5= $3.5
![65 \times 4 = 260](https://tex.z-dn.net/?f=65%20%5Ctimes%204%20%3D%20260)
260 can ride the ferris wheel in 2 hours.
![65 \times 2 = 130](https://tex.z-dn.net/?f=65%20%5Ctimes%202%20%3D%20130)
130 people is the rate per hour.
Answer: No solutions
Step-by-step explanation: If you solve the problem all the way, you get 0 = 4 which is not valid so there is simply no solution
I do not see anything wrong with it
