The box has 2 blue balls, 5 red balls and n yellow balls. Now, you draw a ball from the box. You get 2000 dollors if you draw blue ball, 1000 dollors if you draw red ball, and 0 dollors if you draw yellow ball. If the expect value of draw a ball is 600 dollors, what is the value of n? (A)8 (B)9 (C)10 (D)11 (E)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

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

answer: 193

explanation:

200-7 = 193
