No solution because the lines are parallel.
Answer:
20π ft
Step-by-step explanation:
To find the circumference of the circle given its area, first find its radius.
Substitute given area into the formula:
100π= πr²
Divide both sides by π:
100= r²
Square root both sides:
r= 10 ft
Since we have found the value of the radius, we can substitute r= 10 into the formula above to find the circumference.
Circumference of circle
= 2(π)(10)
= 20π ft
Answer:
One
Step-by-step explanation:
<em>Testing only one variable at a time lets you analyze the results of your experiment to see how much a single change affected the result. If you're testing two variables at a time, you won't be able to tell which variable was responsible for the result.</em>

First you would simplify the left side to get,
ln( ( 3x+1 ) / ( 5+x ) ) = ln 2
Then raise both sides as the power of e, so it would basically cancel out the ln's.
3x+1 / 5+x = 2
3x+1 = 2( 5+x )
3x+1 = 10+2x
x = 9
