Answer:
See explanation below.
Step-by-step explanation:
Let's say,
x = number of tokens required to play one game of ping pong
y = number of token required play one game of pinball
Using the data given, the system of equations are:

Solving the system of equations using substitution method will give us:

So, one game of ping pong required 1 token, whereas one game of pinball required 4 tokens.
Answer:
The equation
has roots –2 and 1/5.
Hence, the option 'a' is the correct answer.
Step-by-step explanation:
Checking the equation

putting x = -2 in the equation





L.H.S=R.H.S
putting x = 1/5 in the equation





L.H.S=R.H.S
As putting x = -2 and x = 1/5 satisfy the equation.
Therefore, the equation
has roots –2 and 1/5.
Hence, the option 'a' is the correct answer.
