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:

$\begin{bmatrix}9x+5y=29\\ 3x+y=7\end{bmatrix}$

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

$y=4\:\:\:,\:\:\:x=1$

So, one game of ping pong required 1 token, whereas one game of pinball required 4 tokens.

Can u please help me??

Answer:

Given GP:

tₙ = (1/3)ⁿ⁻¹

We see that:

t₁ = 1, r = 1/3

Sum of n terms:

Sₙ = t₁(1 - rⁿ)/(1 - r)
Sₙ = [1 - (1/3)ⁿ] / (1 - 1/3) = [1 - (1/3)ⁿ] / (2/3) = 3/2 [1 - (1/3)ⁿ]
Sₙ = 3/2 [1 - (1/3)ⁿ]
