Isolate the x. Note the equal sign. What you do to one side, you do to the other.
Cross multiply
(4/9)(9)(36) = (x/36)(36)(9)
(4)(36) = (x)(9)
Simplify
144 = 9x
Isolate the x. Divide 9 from both sides
144/9 = 9x/9
x = 144/9
x = 16
16 is your answer
hope this helps
The answer is
p + 2 1/2 = 5 because if you plug in 2 1/2 in the equation you get 5 as your answer

Answer:
x = -4, -5, -6, -7...
Step-by-step explanation:
x = all negative integers less than -3
So we want to know what is the difference in magnitude of a large quake M(l) and a small quake M(s) in the Richter scale if the amplitude of a large quake A(l) is 1000 times bigger than the amplitude of a small quake A(s) and the formula is M(l)-M(s)=log{A(l)/A(s)}. So the large amplitude is 1000 bigger than the small amplitude: A(l)=1000*A(s). When we insert that into the formula we get:
M(l)-M(s)=log{1000*A(s) / A(s)}, because the A(s) cancel out, so we get:
M(l)-M(s) = log{1000} = 3.
So the difference in magnitude on the Richter scale is M(l)-M(s)=3.
