Answer:
The measure of the sum of interior angles of a 11-gon is 
.
Each interior angle is approximately 
.
Step-by-step explanation:
A convex polygon has the measure of each interior angles to be less than 
.
But,
sum of interior angles of polygon = (n - 2) x
where n is the number of sides of the polygon.
For a convex 11-gon, we have;
sum of angles of a 11-gon = (11 - 2) x
= 9 x
=
Sum of angles of a 11-gon =
To check: convex polygons' interior angles are less than .
so that,
each interior angle of 11-gon = 
=
N + 5 > 3n = 37
so you're solving for n?
Answer:
x=−1 and y=3 or (-1,3)
WORK:
Let's solve your system by substitution.
y=2x+5;y=−3x
Step: Solve y=2x+5 for y:
y=2x+5
Step: Substitute 2x+5 for y in y=−3x:
y=−3x
2x+5=−3x
2x+5+3x=−3x+3x (Add 3x to both sides)
5x+5=0
5x+5+−5=0+−5(Add -5 to both sides)
5x ÷ 5 = -5÷5 (divide both sides with 5)
x=−1
Step: Substitute −1 for x in y=2x+5:
y=2x+5
y=(2)(−1)+5
y=3(Simplify both sides of the equation)
Answer:
x=−1 and y=3
(Incase you needed to show your work)

Answer:
2356 flowers
Step-by-step explanation:
The number of flowers will be given by
F=1+p/s
Where p is perimeter and s is rhe spacing
Perimeter of a circle is given by
Where r is the radius of the garden.
Substituting 125 ft for radius, rhe perimeter will be
Conversion
Converting ft to inches, we multiply ft by 12 hence 785*12=9420 inches
Number of flowers will then be
F=1+9420/4=1+2355=2356 flowers
Well there are 52.177457 Weeks in a year so 52.177457 x 8 = 417.419656
so the answer is 417.419656
