Answer:

Step-by-step explanation:

Basically [x=8] when a letter (x) is directly by a number.

(8 × 8) - 1 = 64 - 1 = 63

8 × ? = (8 × 8) and 8 as in (x) then you can finish the question.

If ON=8x*8, LM=7x+4, NM=x-5, and OL=3y-6, find the values of x and y for which LMNO must be a parallelogram. The diagram is not

lana66690 [7]

ON = 8x • 8
LM = 7x + 4
NM = x - 5
OL = 3y - 6

OL is congruent & parallel to NM
LM is congruent & parallel to ON

So,
$8x \times 8 = 7x + 4$
Simplify
$64x = 7x + 4$
subtract 7x from both sides
$57x = 4$
divide 57 from both sides
$x = \frac{4}{57}$
Substitute x into equations
$8x \times 8 = 7x + 4 = 4 \frac{28}{57}$

$3y - 6 = x - 5$
$3y - 6 = 4 \frac{28}{57} - 5$
$3y - 6 = - \frac{28}{57}$
NM & OL = -28/57
ON & LM = 4 + (28/57)

In the circle below, if arc AB is congruent to arc CD, chord AB = 16x - 2 and chord CD = 14x + 8, find x.

erastova [34]

Answer:

d. x = 5

Step-by-step explanation:

Chords that subtend congruent arcs are congruent.

<h3>Setup</h3>

Chord lengths are the same:

AB = CD

16x -2 = 14x +8

<h3>Solution</h3>

2x = 10 . . . . . . add 2-14x

x = 5 . . . . . . . . divide by 2
