Ithink is b but not sure it could be c

2x + 3y = 40

-2x + 2y = 20

add

5y = 60

y = 12

-2x + 2y = 20

-2x +2(12) = 20

-2x + 24 = 20

-2x = -4

x = 2

answer is A. x = 2, y = 12

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
