A movie theater has two rooms. Room A has 9 rows of seats with 18 seats in each row. How many seats are there in room A? Fill in the blank. There are ___ seats in Room A. *

162 seats

Step-by-step explanation:

A movie theater has two rooms. Room A has 9 rows of seats with 18 seats in each row.

From the question:

1 row = 18 seats

9 rows = x seats

Cross Multiply

1 row × x = 9 rows × 18 seats

x = 9 rows × 18 seats/1 row

x = 162 seats

There are 162 seats in Room A.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
