Division Property of Equality

Step-by-step explanation:

from the second from last step, we have

2x = -36

if we divide both sides of the equation equally by 2, we get

(2x ) / 2 = (-36) / 2

x = -18 ..., which is exactly the last step that is given in the question

hence in order to get to the last step, we divide both sides of the equality by 2 (a non-zero number).

1010: 3030

is it i think

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
