We suggest starting to prep for the the SAT as early as eighth grade year. It sound early, but if a student plans on taking the SAT several times throughout high school, eighth graders can take a relaxed and long-view approach to prepping, and can plan on taking their first SAT sophomore year.
3x = 3 x 6 should be the equation because 3 x x is 3 x 6
The distance between the campsite and the rest area is 9 miles.
The given parameters:
- <em>Initial speed of the campers, u = 4.5 mph</em>
- <em>Final speed of the campers, v = 4 mph</em>
<em />
Let the time of motion from the campsite to rest area = t (hours)
Time for return trip = t hours + 15 mins
= (t + 0.25) hours
Let the distance between the campsite and rest area = d
d = 4.5t
d = 4(t + 0.25)
4.5t = 4(t + 0.25)
4.5t = 4t + 1
4.5t - 4t = 1
0.5t = 1
t = 2 hours
The distance between the campsite and the rest area is calculated as follows;
d = 4.5t
d = 4.5 x 2
d = 9 miles
Thus, the distance between the campsite and the rest area is 9 miles.

Answer:
<u>If you put a red blood cell in distilled water (100% H2O), there will be a net movement of water </u><u>from a region of higher concentration (100%) to a region of lower concentration </u><u>(the cell with 99.15% H2O). The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic (it contains less salt than the red blood cell) to the red blood cell. The red blood cell will gain water, swell ad then burst. The bursting of the red blood cell is called hemolysis.</u>
