Question

A decorative floor pattern has 1 red square tile surrounded by 12 blue tiles. Write an expression to show how many total red and blue tiles are needed if there are 15 red tiles?
Im confused what the expression would be.

Answer 1

The general equation is that for every red tile, there must be 12 blue ones.

Algebraically this is expressed as b = 12r where r is red and b is blue. Your teacher might like you to express it as y = 12x where y is blue and x is red. The meaning is the same.

For beginners it might be easier to say b = 12r. So if you have 15 reds then r = 15

b = 12 * r

b = 12 * 15

b = 180 blue tiles.

Answer 2

Sorry it was hard to type out but I hope this helps if it is right lol
