Answer:
x=30
Step-by-step explanation:
(30+x)+30+9x=360
We move all terms to the left:
(30+x)+30+9x-(360)=0
We add all the numbers together, and all the variables
(x+30)+9x+30-360=0
We add all the numbers together, and all the variables
9x+(x+30)-330=0
We get rid of parentheses
9x+x+30-330=0
We add all the numbers together, and all the variables
10x-300=0
We move all terms containing x to the left, all other terms to the right
10x=300
x=300/10
x=30
Answer:
50.031 watts
Step-by-step explanation:
Formula
Power = Force * distance / time
The units are critical
distance = meters
time = seconds
force = newtons = kg * m / s^2
Solution
F = m * a
a = 9.81
m = 102 kg
F = 102 * 9.81 = 1000.62 Newtons
T = minute = 60 sec/min * 1 min
T = 60 seconds
d = 3 meters
Power = 1000.62 * 3 / 60
Power = 50.031
