Four friends measure the length of a 6-millimeter-long grain of rice. They record their measurements as shown. Andrey: 7 mm, 5 mm, 6 mm, 8 mm Mariya: 7.41 mm, 8.54 mm, 5.12 mm, 6.23 mm Yuto: 6.1 mm, 5.9 mm, 6.3 mm, 7.2 mm Misaki: 5.843 mm, 6.981 mm, 5.334 mm, 7.632 mm Whose measurements are the most accurate?

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
