Solve for m:
8 = m/4
8 = m/4 is equivalent to m/4 = 8:
m/4 = 8
Multiply both sides of m/4 = 8 by 4:
(4 m)/4 = 4×8
(4 m)/4 = 4/4×m = m:
m = 4×8
4×8 = 32:
Answer: m = 32 thus m - 12 = 32 -12 = 20
Answer:
A total of 720 elk are likely to be infected
Step-by-step explanation:
we shall be using the proportion by survey to estimate the number of infections
From the survey 8 out of 50 are infected. Thus the likelihood of infection is 8/50
We have 4,500 elk to consider. The number of elk likely to be infected will be 8/50 * 4500 = 720

Answer:
The train need to leave Portland at 03:27 am
Step-by-step explanation:
step 1
Find out how long it takes the train to travel from Portland, Oregon, to Los Angeles, California
Remember that
The speed is equal to divide the distance by the time
so
The time is equal to divide the distance by the speed
Let
s ---> the speed in miles per hour
d ---> the distance in miles
t ---> the time in hours
we have
substitute
step 2
Adds 30 minutes (time it takes to get from the train station to her aunt's house)
Remember that
Convert to minutes
step 3
Remember that
Convert to minutes
Subtract 993 minutes from 1,200 minutes
Convert to hours+minutes
so
therefore
The train need to leave Portland at 03:27 am
