Answer:
I think it always work out because they try to manipulate the equation such that you'll get 3
you can actually use other values apart from the ones used
The answer is 1/27
To raise a fraction to a power, raise the numerator and denominator to that power
1 raised to any power equals 1
Answer:
The answer is 13! which equals 6227020800.
So since you gave all of the equations of everyone's amount that they put in, it saves some work.
Let's add up everyone's contribution and then solve for x:

Then since we know the television costs $2,000, we can set this expression equal to that and simplify terms. Then we can solve for x:



So since Ronnie put in 'x', we can say that Ronnie paid $70.
Since Mark put in '2x + 500', we can plug in 70 for x to find that Mark paid $640.
And since Lisa put in '650 + 2x + 500', we can plug in 70 for x again to find that Lisa paid $1,290.
