Kevin is addressing 150 envelopes. during the past 15 minutes, he has addressed 30 envelopes. if he continues at this rate, how many more minutes will it take him to finish addressing the envelopes?
a
240

b
120

c
75

d
60

D. 60

Step-by-step explanation:

So we know that it takes Kevin 15 minutes to address 30 envolopes. So personally, this isn't the easiest way to do it but what I did was multiply 30 by different numbers (30x2; 30x3; 30x4; etc) until one of the answers gave me 150. I soon realized 30x5=150. So I took the number 5 and multplied it by 15 minutes which gave me 75 minutes. If you look at the question carefully it asks how many more minutes will it take him to finish addressing the envelopes. So I subtracted 15 from 75 since Kevin has already spent 15 minutes addressing envelopes.

So it took Kevin 60 more minutes to finish addressing the envelopes.

i really do not know lamo this is great

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.
