Answer:
1/3
Step-by-step explanation:
B. Identity property of division. Everything divided by 1 is itself.
The numbers are x and y
x>y
x=5+2y
x-y=13
so
sub 5+2y for x
5+2y-y=13
5+y=13
y=8
sub back
x-y=13
x-8=13
21=x
the numbres are 21 and 8
Answer: 2.4 as a decimal or 12/5 in fraction form
A line <u>bisector</u> is a <em>straight </em>line that <u>divides</u> a given line into two equal parts. Thus the following steps are required by Naomi to show that point D is <em>equidistant</em> from points A and C.
BD ⊥ AC (given)
BD = 3 units, and AC = 8 units.
BD is the <em>perpendicular</em> bisector of <u>segment</u> AC (given)
Thus,
<BDA ≅ <BDC <em>(right</em> angles formed by a <u>perpendicular</u> bisector)
AD ≅ DC <em>(equal</em> parts of a<em> bisected l</em>ine)
AD ≅ DC = 4 units
Thus joining <u>points</u> B to A, and B to C,
BA ≅ BC.
So that applying <em>Pythagoras</em> theorem to ΔABD, we have:
=
+ 
=
+ 
= 
AB = 5 units
So that,
BA ≅ BC = 5 units
Therefore, it can be <u>concluded</u> that point D is <em>equidistant</em> from points A and C.
