Solve for x:
8 - 5 x = 2 x + 8
Subtract 2 x from both sides:
8 + (-5 x - 2 x) = (2 x - 2 x) + 8
-5 x - 2 x = -7 x:
-7 x + 8 = (2 x - 2 x) + 8
2 x - 2 x = 0:
8 - 7 x = 8
Subtract 8 from both sides:
(8 - 8) - 7 x = 8 - 8
8 - 8 = 0:
-7 x = 8 - 8
8 - 8 = 0:
-7 x = 0
Divide both sides of -7 x = 0 by -7:
(-7 x)/(-7) = 0/(-7)
(-7)/(-7) = 1:
x = 0/(-7)
0/(-7) = 0:
Answer: x = 0
Answer:
Step-by-step explanation:
Power (denoted by P) can be defined as a function of work (denoted by W) and time (denoted by t) using this formula:
Unit of Work = 
Unit for Time = s
Therefore, the Unit of Power
An appropriate unit for power is:
Answer:
39/40
Step-by-step explanation:
Since 39 out of 40 marbles are green, the probability of randomly choosing green is 39/40.
However, the probability becomes 100% when you look into the bag and choose a green marble. (Unless you are blind or unable to distinguish blue from green, in which case the probability remains 39/40.)
Answer:
-4y -12
Step-by-step explanation:
We cannot solve, but we can simplify
3(y-4)-7y
Distribute the 3
3y -12 -7y
Combine like terms
3y-7y -12
-4y -12
Answer:
Step-by-step explanation:
V = pi * r^2 * h
r = 12 mm
h = 5 mm
pi = 3.14
V= 3.14 * 12^2 * 5
V = 3.14 * 144 * 5
V = 2260.8 cm^3
