Answer:
<u>x = 7</u>
Explanation:
Because 25 is a perfect square of 5, we can turn
=
into
=
Since the bases are now both equal, we can completely ignore them, as we are only trying to find x. This leaves us with:
3x - 5 = 2x + 2
All we have to do now is solve for x:
x - 5 = 2 <em>Subtract 2x from both sides.</em>
<u>x = 7</u> <em>Add 5 to both sides.</em>

Answer:
3.5 K
Explanation:
When a sample of a substance releases heat energy, its temperature decreases according to the equation:
where
Q is the heat energy released
m is the mass of the substance
C is the specific heat capacity
is the initial temperature
is the final temperature
For the block of brass in this problem, we have:
m = 0.1 kg is the mass
Q = -56.4 J is the heat energy released (negative since it is released)
C = 380 J/kg K is the specific heat capacity of brass
is the initial temperature
Solving for , we find the final temperature:
