solve:
equation:
or
inequality

53 minutes

Step by step explanation:

The statement “no more than” means less than or equal to. .20 per minute can be written as .20x, x standing for the unknown amount of minutes.

So you would write is as:

.20x+20 {less than or equal to sign} 30.60, then you would solve by taking away 20 from each side giving you .20x{less than it equal to} 10.60 then divide each side by .20

Giving you the ending result of:

X { less than it equal to} 53

So Christian was charged for 53 minutes and this makes it an inequality.

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.

the answer is c

hope this !
