Sandra has 828 math worksheets to do in class and her friend kayla has 828 work also how many does they have in all ?

1656 worksheets

Step-by-step explanation:

To find a total, we need to add Sandra's worksheets and Kayla's worksheet. Let x be the total of worksheets.

828+828=x

Add them up

1656=x

They have a total of 1656 worksheets.

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)
