Question

1) A brick wall has 60 bricks in the bottom row but each row has 3 fewer bricks than the previous one. How
many bricks are in the 12th row?

Answer 1

There are 27 bricks in the 12th row. Hope this helps ! :)

Answer 2

Answer:

24 bricks

Step-by-step explanation:

The equation of the bricks per row can be:

b = 60 - 3r

where r = row and b = bricks.

if r = 12:

$b = 60 - 3 * 12\\b = 60 - 36\\b = 24$
