bi(two)...sector(section). Bisector cuts the segment into two equal sections.

BC = CD definition of perpendicular bisector

BC + CD = BD segment addition postulate

CD + CD = BD substitution

2CD = BD added like terms

2CD = 16 substitution

CD = 8 division property of equality

CD = y + 3 given per graph

y + 3 = 8 transitive property

y = 5 subtraction property

5 1/6 + (7 1/3)l <60

agasfer [191]

Answer:

$l$

Step-by-step explanation:

Given the inequality

$5\dfrac{1}{6}+7\dfrac{1}{3}l$

First, convert mixed numbers to improper fractions:

$5\dfrac{1}{6}=\dfrac{5\cdot 6+1}{6}=\dfrac{31}{6}\\ \\7\dfrac{1}{3}=\dfrac{7\cdot 3+1}{3}=\dfrac{22}{3}$

Now the inequality looks like

$\dfrac{31}{6}+\dfrac{22}{3}l$

Multiply it by 6:

$\dfrac{31}{6}\cdot 6+\dfrac{22}{3}l\cdot 6$

Gina looks at the architectural plan of a four-walled room in which the walls meet each other at right angles. The length of one

Mice21 [21]

The shape of the room is not a square.
Pythagorean Theorem: 17^2+17^2= 578, square root 578 and you'll get 24.04.
The length of the diagonal of the floor of the room in the plan should have been 24.04 in order to be a square.

I NEED HELP!!

Bess [88]

<h2>Answer:</h2>

4x - 6 + 2x = 3(2x - 2)

4x - 6 + 2x = 6x - 6

[ both sides - 6 cancel each other ]

4x + 2x = 6x

6x = 6x

[ both sides 6x cancel each other ]

0 = 0.
