Answer:
x = 120°
Step-by-step explanation:
The equation is given to you:
The sum of the interior angles can be found using the equation:
Sum = (n - 2)180
Note that:
n = # of sides.
Plug in 6 for n in the equation.
∑ = (6 - 2)180
First, solve for the parenthesis:
∑ = (4)180
Next, multiply:
∑ = 4 * 180
∑ = 720
You are solving for one angle. Note that there are 6 angles. Divide the sum of the angles with 6:
720/6 = 120
120° is your answer.

There are 3 answers: Choice A, Choice D, Choice F</h3>
Explanation:
2 & 1/2 = 2.5
10 + (-2.5) can be represented by starting with 10 and then dropping by 2.5, which is what choice A is saying
or we can start with -2.5 and add on 10. This works because we can add numbers in any order, example: 2+3 = 3+2 = 5. So starting with -2.5 and adding on 10 is represented by choice D's and choice F's examples
690 because 86 is rounded up to 90
Answer:
2>y
Step-by-step explanation:
4/9>y/18
Here u cross multiple
4*18 >9*y
72>9y
the you divide both sides by 9
72/9>9y/9
8>y
X=t/7
x is the cost for each of the friends plus you (me)
t is the total amount of me and my friends
7 is me and my friends
Hope this helps you •з•
