A regular pentagon shares a common center with a regular hexagon. If `bar(LM)` || `bar(AB)`, across how many lines of reflection
choli [55]

our lines of symmetry is made limited by the presence of the pentagon. If we slice the pentagon into two, the only line of symmetry we could create would be the line intersecting O and the median of LM. Other lines would not create a symmetrical half.

Therefore the line of reflection is only 1.

What is the slope of line 2x-3y=19.<br>​
KengaRu [80]

Answer:

\frac{2}{3}

Step-by-step explanation:

Given Equation of line: y=mx+c,

where m = slope of line.

So, we will have to make y the subject to find the slope.

2x-3y=19\\2x-3y-2x=19-2x\\-3y=-2x+19\\y=\frac{-2x+19}{-3} \\y=\frac{2}{3} x-\frac{19}{3}

From here, we can see the slope of the line is \frac{2}{3}.

Use the circle shown to answer the question.
lakkis [162]

The value of x in the angle ABC is 25.

<h3>How to find the angles in circle?</h3>

The measure of an inscribed angle is half the measure of the arc intercept.

In other words, the measure of an inscribed angle in a circle equals half the measure of its intercepted arc.

Hence, lets find the value of x in the angle ABC.

Therefore,

m∠ABC = 1 / 2 (arc AC)

arc AC = 76 degrees.

Hence,

m∠ABC = 1 / 2 × 76

2x - 12 = 1 / 2 × 76

2x - 12 = 38

add 12 to both sides of the equation

2x - 12 = 38

2x - 12 + 12 = 38 + 12

2x = 50

divide both sides by 2

2x / 2 = 50 / 2

x = 25

What is 3 3/4 x = 1 1/4
kumpel [21]

Answer:

\frac{1}{3}

Step-by-step explanation:

1. Convert both mixed numbers into improper fractions:

\frac{15}{4} x = \frac{5}{4}

2. Multiply both sides by 4:

4 · \frac{15}{4} x=\frac{5}{4} · 4

15x = 5

3. Isolate x:

x = 1/3

hope this helps!
