16r6sc/8r2s6 Which expression is equivalent to the given expression? Assume the denominator does not equal zero. A. B. C. D.

Answers

Answer:

B.  

Step-by-step explanation:

The required expression is equivalent to the given expression is C.

An equivalent expression for 16r6sc/8r2s6 is to determine.

What is the Ratio?

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Numerator = it is the term positioned above in the ratio
Denominator = it is the term positioned below in the ratio

Here,  
= 16r6sc/8r2s6
Factored 16 into 8 * 2
= 8*2r6sc/8r2s6
Rearrange the numerator in order to simplify relative to denominator.
=8r2s6c/8r2s6
8r2s6 are common in the denominator and the numerator of the ratio denominator does not equal zero so it implies
=c/1

Thus the required expression is equivalent to the given expression is C.

2x-1+9x+3=57 solve for X

Answers

Answer:

x = 5

Step-by-step explanation:

2x-1+9x+3=57

2x+9x=57+1-3

11x=55

x= 55/11

x= 5

Answer:

x = 5

Step-by-step explanation:

Simplifying 2x + -1 + 9x + 3 = 57

Reorder the terms: -1 + 3 + 2x + 9x = 57

Combine like terms: -1 + 3 = 2 2 + 2x + 9x = 57

Combine like terms: 2x + 9x = 11x 2 + 11x = 57

Solving 2 + 11x = 57

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation. 2 + -2 + 11x = 57 + -2

Combine like terms: 2 + -2 = 0 0 + 11x = 57 + -2 11x = 57 + -2

Combine like terms: 57 + -2 = 55 11x = 55

Divide each side by '11'. x = 5

Simplifying x = 5

B. alternate interior angles theorem

C. alternate exterior angles theorem

D. corresponding angles postulate

E. linear pair postulate

Answers

Answer:

C. Alternate Exterior Angles Theorem

Step-by-step explanation:

I took the test

The corresponding angles postulate and the vertical angles theorem are proving ∠6 = ∠13. Therefore, options B and D are correct answer.

From the given figure, lines GN and FH are intersecting by the line segments KL and JM.

What are angles of parallel lines?

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

From the given figure, we can see that

∠6 = ∠10 (Corresponding angles are congruent)

∠10 = ∠13 (Vertical angles are congruent)

Now, ∠6 = ∠10 = ∠13

The corresponding angles postulate and the vertical angles theorem are proving ∠6 = ∠13. Therefore, options B and D are correct answer.

–4(x + 3) = 4(–x – 1)

Answers

Answer:

1 and 5

Step-by-step explanation:

1. 6x + 1 = 3(2x - 4)

6x + 1 = 6x - 12

6x + 13 = 6x

-6x         -6x

    13 = 0x

2. 2-5x = 7x - 12

    2 = 12x - 12

    14 = 12x

Here are three lamps.
lamp C
lamp B
lamp A
Lamp A flashes every 20 seconds.
Lamp B flashes every 45 seconds.
Lamp C flashes every 120 seconds.
The three lamps start flashing at the same time.
How many times in one hour will the three lamps flash at the same time?​

Answers

Answer with step-by-step explanation:

First of all, we need to calculate how many times the 3 lamps flash in a minute. We can do this by finding their LCM (least common multiple), which is 360. 360 is equivalent to 6 minutes, so that is going to be our test time. Lamp a flashes every 20 seconds, so 360/20 = 18 flashes. Then, 360/45 = 8 flashes. Finally, 360/120 = 3 flashes. 18 + 8 + 3 = 29 flashes per 6 minutes. If so, we multiply 29 by 10, because 60 minutes per hour ÷ 6 minutes = 10. So 29 × 10 = 290 flashes per hour

Let's see what to do buddy...

_________________________________ Step (1)

First we must find the measure of x

[tex](3x - 5) + (x + 1) = 180[/tex]

[tex]4x - 4 = 180[/tex]

Both sides plus 4

[tex]4x = 184[/tex]

Divided both sides by 4

[tex]x = \frac{184}{4} \\ [/tex]

[tex]x = 46[/tex]

_________________________________

Step (2)

Now we must find the RQS Angle measure :

Angle ( RQS ) = 46 + 1 = 47

_________________________________

Step (3)

QT bisects RQS ;

So the resulting angles are :

[tex] \frac{47}{2} = 23.5 \\ [/tex]

Not enough information to make a conclusion. What writers struggle to express through numerous newspaper columns, the cartoon manages in a pointed one-liner. Little wonder then, that the first thing most of us like to see when we pick up a newspaper is the cartoon. Simple though it may seem, making a cartoon is an art that requires a combination of hard work, training and a good sense of humour. Cartoonists say that the cartoons that make us laugh the most are in fact the cartoons that are hardest to make. Even celebrated cartoonists like R.K.Laxman admit that making a cartoon is not a piece of cake. Laxman says he has to wait for over six hours, which includes spending a lot of time scanning newspapers and television channels before any idea strikes him.So how does one become a cartoonist? Which of us has the talent to make it? How can we master the rib-tickling strokes and the witty one-liners? How can we make people smile or laugh? There are few colleges or schools for cartoonists. Most cartoonists come from art colleges, while some learn the craft on their own. Most established cartoonists are of the view that no institute can teach you to make a cartoon. "You can pick up the craft, you may learn to sketch and draw in institutes, but no one can teach anyone how to make a good cartoon," says Uday Shanker, a cartoonist with Navbharat Times. While basics, like drawing and sketching can be learnt in an art college, and are important skills, these alone, do not make a good cartoonist. Because it's a question of one's creativity and sense of humour; two qualities one simply may not have. The advice established cartoonists give is that just because you can sketch, don't take it for granted that you will become a cartoonist.
