There's an auditorium with rows of eight in each row . There's between 70-150 seats . How many rows of seats can fit in the auditorium? How can you find the least possible number of rows in the auditorium?

Between 9 and 20rows; at least of 9 rows

Step-by-step explanation:

Since there are eight seats in a row and in the auditorium we have about 70 to 150seats, the number of rows of seats that can fit into the auditorium will be between 70/8 and 150/8 rows which is equivalent to 8.75 and 19.75 rows in the auditorium. This is approximately 9 to 20 rows.

This shows that about 9 to 20 rows can fit into the auditorium.

The least possible number of rows means the lowest number of rows we can have in the auditorium which is 9rows according to the calculation above

r=0

Step-by-step explanation:

-4r-6= -(6-r)

-4r-6= -6+r

-4r=r

-4r-r=0

-5r=0

r=0
