Answer:
<u>Option 4:</u> -6.1 - (-3.13)
Step-by-step explanation:
Let's solve each option individually to see if -2.97 fits as the solution:
-6.1 - 3.13 = -9.23
-6.1 - (-31.3) = 25.2
-0.61 - (-3.13) = 2.52
<u>-6.1 - (-3.13) = </u><u>-2.97 </u>
As you can see, -2.97 is the answer to Option 4.
So, the decimal -2.97 is the solution to the subtraction problem in Option 4.
Answer:
82050 people/mi^2
Step-by-step explanation:
The population of the US is 328.2 million people and the area of the US is 4000 mi^2 as given. The population density is found by (population)/(area), so we input our values in:
Population density = 328, 200, 000/4000 = 82050 people/mi^2
I hope this helps! :)
Solve for m:
(-3 m)/7 = 12
Multiply both sides of (-3 m)/7 = 12 by -7/3:
(-7 (-3) m)/(3×7) = (-7)/3×12
(-7)/3×(-3)/7 = (-7 (-3))/(3×7):
(-7 (-3))/(3×7) m = (-7)/3×12
(-7)/3×12 = (-7×12)/3:
(-7 (-3) m)/(3×7) = (-7×12)/3
(-7)/7 = (7 (-1))/7 = -1:
(-3-1 m)/3 = (-7×12)/3
(-3)/3 = (3 (-1))/3 = -1:
--1 m = (-7×12)/3
(-1)^2 = 1:
m = (-7×12)/3
12/3 = (3×4)/3 = 4:
m = -74
-7×4 = -28:
Answer: m = -28
I believe that you already found the correct answer. But if it isn't I would just try 0.15.
