In an indoor soccer stadium, there are 20 seats in the first row and 31 seats in the second row. Every

Finger [1]

Step-by-step Solution for Part-a:

Row-1: 20 seats
Row-2: 20 + 11
Row-x: 20 + (11x - 11)

Since the number of rows in rows x is 20 + (11x - 11), the formula to calculate the number of seats in each row is 20 + (11x - 11).

Step-by-step Solution for Part-b:

y rows = 174 seats
Obtained rule from part-a: 20 + (11y - 11)

<u>Solution:</u>

20 + (11y - 11) = 174 rows
=> 20 + 11y - 11 = 174 rows
=> 9 + 11y = 174 rows
=> 11y = 174 - 9 rows
=> 11y = 165
=> y = 165/11
=> y = 15

Hence, the row which has 174 seats is row 15.

Is y varies directly as x, and y is 18 when x is 5 witch expression can be used to find the value of y when x is 11?

Svet_ta [14]

As the variation is direct we have:
$y = k * x
$
Where,
k: proportionality constant
We must find the value of k.
For this we use the following data:
y is 18 when x is 5.
Substituting values we have:
$18 = k * 5
$
From here, let's clear k:
$k = 18/5

k = 3.6
$
Then, replacing values we have:
$y = 3.6 * x
$
For x = 11 we have:
$y = 3.6 * 11

y = 39.6$
Answer:
An expression that can be used to find the value of y when x is 11 is:
$y = 3.6 * x
$
When x = 11 we have:
$y = 39.6$
