Step-by-step explanation:

Two composite numbers that are relatively prime are 10 and 21
Answer: x = 7 , y = 3
Step-by-step explanation:
Since they are integers , it means they are whole numbers.
Let the first number be x and the second number be y , then ,interpreting the question , we have
x + y = 10 ...................................... equation 1
x - y = 4 ........................................ equation 2
solving the resulting simultaneous linear equation by substitution method.
From equation 2 , make x the subject of the formula, that is
x = 4 + y .............. equation 3
substitute x = 4 + y into equation 1 , equation 1 becomes
4 + y + y = 10
4 + 2y = 10
subtract 4 from both sides
2y = 10 - 4
2y = 6
divide through by 2
y = 3
substitute y = 3 into equation 3 to find the value of x
x = 4 + y
x = 4 + 3
x = 7
Therefore : x= 7 and y = 3
Answer:
The difference between the number of pages that Darla and Juan read are <u>VI pages</u>.
Step-by-step explanation:
Given:
Darla told her teacher that she had read XLV pages in her library book.
Juan said that he had read XXXIX pages.
Now, to get the difference between the number of pages that Darla read and Juan read.
As, we see the number of pages are in roman numeral symbols.
So, we convert them in numbers first to calculate:
Darla read = XLV pages.
Darla read = 45 pages.
Now,
Juan read = XXXIX pages.
Juan read = 39 pages.
So, to get the difference between the number of pages by subtracting:

<em>Thus, the difference between the number of pages = 6 pages.</em>
Now, converting it into roman numerals:
6 pages = VI pages.
Therefore, the difference between the number of pages that Darla and Juan read are VI pages.
