<span>I am not sure about that x value stuff....but time = distance / speed......time = 495/45 = 11 hrs to reach home </span>
5.8/100 = x/18,801,310 ==================================>
x = 1,090,475.98
=================================>
18,801,310 + 1,090,475.98 = 19,891,785.98 population at 2014
=============================>
19,891,785.98/53,625 =
about 371 people per square mile in 2014
=================================>
18,801,310/53,625 =
about 351 people per square mile in 2010
=================================>
371 - 351 = 20 people per square mile increase from 2010 to 2014
Take x-2=0
x=2
put the value of x in the equation
2^2 + 3(2) + k =0
4+6+k=0
10+k=0
k= -10
hope you understand
You set the expressions equal to each other since they are congruent, then solve.
5x + 24 = 9x - 17
First subtract 24 from both sides to get
5x = 9x - 41
The subtract 9x from both sides to get
-4x = -41
Then divide both sides by -4 to get
x = 41/4 or as a decimal x = 10.25
