The school had 366 chairs and 12 classrooms. How many chairs could they put in each classroom?

Step-by-step explanation:

Divide 366 by 12 for your answer.

366/12=30.5

You can't place half a chair, so round down for 30 chairs per classroom.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
