Answer from: cheergirlpayton3510

Step-by-step explanation:

Begin by assigning expressions for both Mike and June. If Mike has twice as many birds as June, then June has x birds and Mike has 2x birds. "After he gave 15 paper birds to June" means we are subtracting 15 from what he has, which is 2x. Therefore, the first part (or the left side of our equation) looks like this: 2x - 15 =

Now what he has left is what goes on the right side of the equals sign. If what Mike has left is half as many as June, then 1/2x goes on the right. Our equation then is

$2x-15=\frac{1}{2}x$

Combine like terms to get

$\frac{3}{2}x=15$

Multiply both sides by 2/3 to get that x = 10. If x is June's number of paper birds, and Mike's is 2x, then Mike has 20. Together they have 30.

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.
