Well if we look at these equations we can see that D is the only appropriate answer considering 23 + 112 = 135 bracelets.
Yes the equation works as well
b - 23 = 112
we add 23 to both sides
b - 23 + 23 = 112 + 23
b = 135
Answer:
X=2, Y=-15
Step-by-step explanation:
-7x+y=-19
-2x+3y=-19
------------------
-3(-7x+y)=-19
-2x+3y=-19
---------------------
21x-3y=57
-2x+3y=-19
---------------------
19x = 38
19x/19=38/19
x=2
now plug 2 into x of the second equation to get y=-15
(N-2)*180/n
Octagon has 8 sides
(8-2)*180/8
=135
I believe the answer is x+20.
Answer:
is equidistant from
and
.
Step-by-step explanation:
Given that the point
which is on the perpendicular bisector of the line segment having endpoints at
and
.
The given situation can be represented as the diagram as attached in the answer area.
Referring to the
:
(As it is the perpendicular bisector)
(As it is the perpendicular bisector)
Also, the side
is the common side.
Therefore by
congruence, 
As per the properties of congruent triangles:
Side
= Side 
and
are nothing but the distance of the point
from the end points
and
which are proved to be equal to each other.
Therefore, we can conclude that:
is equidistant from
and
.
