Answer:
x = - 9
Step-by-step explanation:
Given
= - 3 ( multiply both sides by 3 to clear the fraction )
x = - 9
10(3+10с)
This expression has a common factor of 10
Answer:
About 90.73 meters/min.
Step-by-step explanation:
Dimensional analysis is done by multiplying the wanted unit over the current unit in equal measure, or the other way around.
First, we will convert feet to meters, using that 1 ft = .4048 m.
32ft/6.45sec * .3048m/1ft = 32/6.45sec * .3048m = 9.7536m/6.45 sec.
Second, we convert seconds to minutes, using that 60 sec = 1 min.
9.7536m/6.45sec * 60sec/1min = 9.7536*60m/6.45min ≈ 90.7311627m/min.
Both the median and mean=27 so median or mean would work.
4 + 3x = 12
3x = 12 - 4
3x = 8
x = 8/3
x = 2,6 grams
