Answer:

x1 = 3 \\ y1  = 10 \\ x2 = 5 \\ y2 = 12 \\ y - y1 =  \frac{y2 - y1}{x2 - x1} (x - x1) \\ y - 10 =  \frac{2}{2} (x - 5) \\ y = x - 5 + 10 = x + 5

A theatre has seats arranged in rows of 24, 382 people attend a show at the theatre. What is the smallest number of rows that is
kipiarov [429]

Answer:

A minimum of 16 rows are needed

Step-by-step explanation:

Here, we want to calculate the number of rows minimum that could seat 382 people in rows of 24 seats.

Mathematically, what we need to do here is to make a division.

We shall divide the number of people by the number of seats in a row so that we can get the number of rows needed.

Mathematically, that would be; 382/24 = 15 22/24

We are looking at a minimum number.

So we can see that 15 rows will be filled, with an extra 22 seats in the next row leaving only 2 seats in the next row unoccupied.

So we can see that the minimum number of rows required is 16 rows
