X=2 you just divide both sides
Hope this will help you.
So, you already know how long it takes him to run 100 meters,9.91 seconds.
In order to get the answer, you need to multiply 26 miles by 9.91 seconds.
The answer you would get from doing that is 257.66 minutes.
If you want to simplify it into hours, simplify it by 60 minutes.
4 hours and 29 minutes is the answer.
20 adults and 50 kids.

Ax+By=C [Use the standard form of a linear equation]
x+y=C so, x+(C-x)=C [also use this formula]
.
$5.50x+$4.00y=$310 [plug-in the values]
Since x+(C-y)=C, than x+y=70 or x+(70-x)=70
.
5.50x+4.00(70-x)=310 [substitute (70-x) for y and simplify]
5.50x+280-4x=310
5.50-4=310-280 [solve for x]
1.5x=30
x=20 adults
and
y=(70-x)=70-20=50 kids under 12.

Answer:
the estimated amount of electricity consumed per person is 12,828.95 million kh
Step-by-step explanation:
The computation of the electricity consumed per person is shown below:
= Electricity consumed in United states ÷ population of the united states
= 3,900000 million of kilowatt hours ÷ 304 million
= 12,828.95 million kh
Hence, the estimated amount of electricity consumed per person is 12,828.95 million kh
