Answer:
He refers by 'pulse' the way you can check the state about something that is not visible at once, like when you check somebody's heart condition just by checking his pulse or heartbeat. Even though he lived in the continent and he could check the state of things as a journalist, he could imagine or make an idea for himself about what was the state of things in places he couldn't see or visit by himself. Then, this idea would come from the people who used railroads which crossed the continent by then. It is also a way to describe media in his times because he could know about something that was happening somewhere else through the fastest transportation mean in his time. As public transportation means, people who used railroads also brought news from they were coming from, so locals could know the whereabouts from a distant place that they could know or check by themselves.
Explanation:
I used the term 'pulse' to explain what does Whitman mean on this statement.
Answer:
<h3>He needs 5 more months of savings for him to reach his goal. </h3>
Explanation:
Given the equation that models Damon's saving plan as y = 500 + 400x where x represents the number of months since last week and y represents the total amount he's saved for the vacation. Since he estimates that he'll need about $2,500 for the trip, therefore y = $2,500.
In order to determine how many more months of saving (x) it will take to reach his goal, the following steps must be taken by Damon (Damon true statements)
Step 1:
y = 500 + 400x
Step 2: Subtract 500 from both sides
y - 500 = 500 + 400x - 500
y-500 = 400x
Step 3: Substitute y = $2500 into the resulting equation and solve for x
400x = 2500-500
Step 4: Take the difference of the value at the right hand side of the equation
400x = 2000
Step 5: Divide both sides by the coefficient of x (i.e 400)

Step 6: Get the value of x
x = 5
