Audrey's parents give her $5 to play video games at the mall. each games costs a quarter to play. which choice is not a correct method for determining the total #of games she can play. a. take the #of dollars she has and divide it by 1/4. b. take the # of dollars she has and multiply it by 4. c. take the # of dollars she has and divide it by 0.25. d. take the # of dollars she has and multiply by 0.25

Step-by-step explanation:

If answer A works then so will Answer A. The reason is because 1/4 and 0.25 are equal to one another. The only comment you should recognize is that

5/0.25 is a whole lot easier to do than 5/(1/4)

B is the same thing as C when you apply the division by fractions rule.

D is the odd method out. Instead of 20 games (5 * 4) she will only get to play 4. That because she has 5 dollars and if you multiply by 0.25 you get 1.25 games

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
