Answer:
#6 is D
#7 is A
Step-by-step explanation:
#6
-1/3(6x+15)-3
Distribute the -1/3
-1/3 times 6x is -2x
-1/3 times 15 is -5
-2x-5-3
-2x=8
#7
-12z-5z=85
COmbine like terms
-17z=85
Divide both sides by -17
z=-5
the magnitude of an earthquake that is 5,011 times more intense than a standard earthquake is 3.7
<u>Step-by-step explanation:</u>
Here we have , to find the magnitude of an earthquake that is 5,011 times more intense than a standard earthquake . Let's find out:
We know that , Value of earthquake is given by formula
⇒
, Where M is magnitude of earthquake
is the measured magnitude of intensity of earthquake .
is the standard magnitude of intensity of earthquake .
According to question ,
, Hence
⇒ 
⇒ 
⇒ 
⇒
{ On rounding off we get }
⇒ 
Therefore , the magnitude of an earthquake that is 5,011 times more intense than a standard earthquake is 3.7
