If a newspaper costs $0.60 and you only have $5.00 in quarters, how many cents would you lose out on because the vending machine doesn't give back any change?

Step-by-step explanation:

500 / 4 = 20 quarters we have

for the newspaper we will put only 3 quarters to machine

3 * 25 = 75 cents

75 - 60 = 15 cents lose

still we have 17 quarters

step-by-step explanation:

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)
