A couch and coffee table cost a total of $996. The cost of the couch is two times the cost of the coffee table. Find the cost of each item.

the cost of the couch is 664 and the cost of the coffe table is 332

Step-by-step explanation:

X is the cost of the coffee table and 2x is the cost of the couch (which is two times more than the coffee table)

2x + x = $996

3x = $996

x = 996/ 3

x = $332 (this is what the coffee table cost)

2x => 2(332)

2x => $664 (the cost of the couch which is two times the cost of the coffee table)

together, $332 + $664 = $996 total

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
