You want to make the denominator of the fractions to be equal to each other.
(2/n+8)+(4/n+1) multiply n+1 by n+8, and multiply n+8 by n+1
(4n+32/n^2+8)+(2n+2/n^2+8) Now that the denominators are equal we can solve the numinator by adding like terms.
4n+2n=6n, 32+2=34
Your final answer is 2(3n+17)/n^2+8
Answer:
The amount of change she received was 
dollar.
Step-by-step explanation:
Price of each carton of milk is 
cents and she bought 3 cartons of milk.
We know that, <u>1 dollar = 100 cents</u>
So, 1 cent = 
dollar.
and cents 
dollar.
Thus, <u>the total price of 3 cartons of milk</u> 
dollar.
She gave the cashier $10.
So, the amount of change she received 
dollar.
Answer:
X = 42
Step-by-step explanation:
1/3 / 42 = 126
36 + 6 = 42
42 - 6 = 36
so the answer is 42
Answer:
(0,-1)
Step-by-step explanation:
Let the ends of the line segments be A(-4,3) and B(5,-6).
Ratio=4:5
By the concept of cordinate geometry,
x=(mx2+nx1)/(m+n)
y=(my2+ny1)/(m+n)
where m and n is the ratio m:n.
So, here the cordinates are
x={4(5)+5(-4)}/(4+5)
x=(20–20)/9
x=0
y={4(-6)+5(3)}/9
y={-24+15}/9
y=(-9)/9
y=(-1)
Therefore the cordinates of the point that divides the given line segment in the ratio 4 : 5 is (0,-1)
