Answer:

David gets 28 more than Dan

Step-by-step explanation:

Jim: Dan : David: total

3   :    1    :  5       : 3+1+5 = 9

Jim gets 21

21/3 = 7

Multiply each number by 7

Jim: Dan : David: total

3*7 :  1*7  :  5 *7  :  9*7

21  :   7     :  35   :  63

David has 35 and Dan has 7

35-7 = 28

David gets 28 more than Dan

What is the answer to 7/8+4.2-4/5 equals what
natta225 [31]
So, first turn your fractions into decimals. ⅞ = 0.875 which rounded is 0.88. 4/5 = 0.8. Next, put the decimals into the equation to replace the fractions. 0.88 + 4.2 - 0.8. Next solve the problem. So 0.88 + 4.2 = 5.08. Now your equation should look like this 5.08 - 0.8. Then subtract 0.8 from 5.08 which gives you 4.28. So 4.28 is your answer.

It’s not “analyzes the paper topic” I got it wrong in Edgeunity it should be “explains the papers topic”
alexandr1967 [171]

Answer:

Step-by-step explanation:

The correct answer for the first question is, what does the audience want to know? She wants the audience to know that she is preparing to write an article for his school newspaper. A thesis statement is a sentence that most likely explains the papers topic and knowing the audience will help her use the right words and connotations to provide the best report to her teacher.
