Answer:
Thus the number of books at $2 is 9 books.
Step-by-step explanation:
The number of the book purchased = 15 books
Total amount spend to buy the books = $34
The prices of books are $2 and $3.
Let the number of books purchased at price $2 = x
Let the number of books purchased at price $3 = y
Now we have to find the number of books that is bought at $2.
Below are the equations.
x + y = 15
2x + 3y = 34
Now solve for the x,
x + y = 15
y = 15 – x
Now insert it in the 2x + 3y = 34
2x + 3(15-x) = 34
2x + 45 – 3x = 34
-x = 34 – 45
x = 9
Thus the number of books at $2 is 9 books.
Answer:
4--2/4--4
6/8=3/4
y=3/4 x +c
4=3/4(4)+c
4=3+c
4-3=c
1=c
y=3/4x+1

Answer:
positive
Step-by-step explanation:
if you time the three by a postive then times that by a negetive you get a negitive if you time by two negitives you get postive
Answer:
You are correct great job! I believe you did
1/4 × 1/9 = 1/36 If so thats exactly the right method!
soo this may seem a little awkwark but it still should provide the same resault however its faster :)
so we have
(48x^5-16x^3+40x)/8x
What we are going to be doing is factoring out any and all possibilities for
(48x^5-16x^3+40x)
first factor
(8x(6x^4-2x^2+5))/8x
when we get to this step simplify 8x
we are left with 6x^4-2x^2+5
in order to get an answer that would often be used by long devision just get rid of the +5
This is just a remainder using long devision your instructer may ask for
6x^4-2x^2
Hope it helps
