Answer:

12 km

Step-by-step explanation:

5h 24min = 5.4 hr
time = distance / speed

--------------------------------

time out + time back = total time

d/5 + d/4 = 5.4

multiply both sides by 20 to clear the fractions

4d + 5d = 108

9d = 108

Divide both sides by 9

d = 12 km

I would love if someone would help me

I’m hoping this helps (but hopefully now you can give the brainliest to the person above)
I’m not very familiar with the square roots method but I believe you try and isolate the term that is squared.

A container of beads contains: 8 red beads, 6 yellow beads, and 6 green beads. A bead will be drawn from the basket and replaced

77julia77 [94]

Answer:

Because of probability, a green or red bead would be drawn 14/20 times because there are 20 total beads and adding together the numbers for green and red. From this, if you multiply by 3/3 you can see that 42/60 times it will be a green bead. A reasonable prediction for green beads would then be 42 times. Hope it helps :D
