Katie is Celine glasses of lemonade for $0.50 she sells between 20 and 40 glasses in an hour if she sells lemonade for 6 hours what is the reasonable amount of money for her to make

$90

Step-by-step explanation:

Let’s find the avg if 20 and 40 to get an apron estimate on the number of glasses she sold in an hour:

20+49/2=60/2=30

She sold about 30 glasses in an hour

For 6 hours we would have to do:6*30=180

About 180 glasses in 6 hours

To find how much money she made:0.5*180=90

Hope this helps!

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

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)
