Hello!
First, let's write the problem.

Subtract 3x from both sides.


The opposite of division is multiplication, so we are going to multiply in order to undo the fraction.

Our final answer would be,

Answer:
2.113 and -0.446
Step-by-step explanation:
you have to use the formula x=-(b)+ or - the sqaure root of (b) squared-4 (a)(c) all over 2 (a).
Stoopid, its 200 centimeters
<span>n >= 1125
First, make an equation to express the money raised after expenses.
55n - 15n + 10000 = m
The above expression can be read as "55 dollars per running is raised, but 15 dollars is spent per running to support them. Plus we get 10000 as a constant regardless of how many runner we have." Now convert that to an inequality for at least 55000 to be raised.
55n - 15n + 10000 >= 55000
Now solve for n
55n - 15n + 10000 >= 55000
40n + 10000 >= 55000
40n >= 45000
n >= 1125
So there needs to be at least 1125 runners in order to meet the goal of $55,000.</span>
