Answer will get brainliest! asap at track practice, runners were to walk or jog twenty laps. sam jogged 0.29 of the laps, jim jogged 3/11 of the laps, sue jogged 0.26 of the laps, and bill jogged 2/7 . list the runners in order from least to greatest number of laps walked. a) sue, bill, jim, sam b) sam, jim, bill, sue c) sue, jim, bill, sam d) sam, bill, jim, sue

Sam,bill,Jim, sue

Step-by-step explanation:

2/7=.285

0.29

0.26

3/11=0.2727

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
