I’m guessing you need the area which is 502.65
(The formula is 2x pi x r + 2 x pi x r squared
Hello there!
An equation to model this situation is 3n - 50 = -11
The unknown number has a value of 13.
Okay, so let's start by breaking down the question - we'll use <em>n</em> to model the unknown number.
-50 added to three times an unknown number equals -11?
This means we are adding -50 to something else. (We can use + -50 or - 50 since they are the same thing, I'll use - 50 since it's easier to follow.)
-50 added to three times an unknown number equals -11?
This phrase can be modeled as 3n. This is what we are taking 50 from, so we can add that to the end of the equation so far.
3n - 50
-50 added to three times an unknown number equals -11?
This can means the equation equals -11. We can model it as = -11. Now, let's add it to our equation.
3n - 50 = -11
Now, solve for n.
You want to start by canceling -50 out on the left side, so n is on it's own side, and to do this you add 50 to both sides.
3n - 50 + 50 = -11 + 50
3n = 39
To finish isolating n, divide both sides of the equation by 3.
3÷3n = 39÷3
n = 13.
I hope this helps and have a great day!

Step-by-step explanation:
Hi there!
We want to solve for c (find the value of c) in 15=
To do that, isolate 1c (also written as c) on one side.
We can add 18 to both sides to remove it from the right side
15=-18
+18 +18
_______________
33=
You want to know how to solve an equation where the coefficient of a term is a fraction
Remember that we want to find the value of 1c.
Multiplying a fraction by its reciprocal (the 'flipped' version of that fraction) will give 1.
For example, multiplying by (the reciprocal of ) will give:
So therefore, we should multiply both sides by the reciprocal of , which would be
Therefore,
Multiply
=
Simplify the fractions
88=c
Hope this helps!
The answer is C I had that same test question
