Options A,C and E.

Step-by-step explanation:

The given equation is

$2n-9.2=n+\dfrac{4}{5}$

Let n be the unknown number, then

Twice a number minus nine and two-tenths is the same as the number plus four-fifths.

$2n-9.2=n+\dfrac{4}{5}$

So, option A is correct.

Nine point two decreased by double a number is the same as the number added to four-fifths.

$9.2-2n=n+\dfrac{4}{5}$

Nine point two less than twice a number is equal to the number added to four-fifths.

$2n-9.2=n+\dfrac{4}{5}$

So, option C is correct.

Two times the difference of a number and nine and two-tenths is equal to the number plus four-fifths.

$2(n-9.2)=n+\dfrac{4}{5}$

Double a number decreased by nine and two-tenths is the same as the sum of four-fifths and the number.

$2n-9.2=n+\dfrac{4}{5}$

So, option E is correct.

Therefore, the correct options are A,C and E.

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
