Answer:

71, 72, 73, 74 . for details, check below

Step-by-step explanation:

a) Let's assume that among the four consecutive numbers, the first one is x,

so, the four consecutive numbers should be:

x
x+1
x+2
x+3.

According to the question,

(x) + (x + 1) + (x + 2) + (x + 3) = 290

(x) + (x + 1) + (x + 2) + (x + 3) = 290

4x + 6 = 290

4x = 284

x = 284÷ 4

x = 71.

So, the numbers are,

71, 72, 73, 74

The computation shows that the year that Helike disappeared is 2248 years in between.

<h3>How to calculate the value?</h3>

From the information, Helike disappearance was denoted as -1/5w. The year that civil year ended was represented as c + 1/4c.

This implies that year Helike disappeared will be:

= c + 1/4c - +-1/5w)

= 2248 years.

Here is the complete question:

The year the Greek city of Helike disappeared is -⅕ times the year the US Civil War ended. Let w represent the year the Civil War ended. Write an expression in terms of w to represent the year of Helike’s disappearance.

Part G

Use the results from Part E and Part F to determine the year Helike disappeared. Express your answer in terms of BC or AD.

Part H

Using the results from parts D through G, write an expression that represents the number of years elapsed between the disappearance of the Greek city of Helike and the end of the US Civil War. Write the expression in terms of c and w. Then solve the expression to find out how many years separate these two events.
