Answer:
To divide fractions you have to multiply by the reciprocal of the second fraction:
(1/9)-(1/n) * 9/(1+9)
Now, focus on the left side of the multiplication sign. In order to subtract the 2 fractions, you need a common denominator, 9n. Multiply each fraction to make their denominators equal to 9n:
1/9 * n/n = n/9n
1/n * 9/9 = 9/9n
Now it should look like this: (n/9n) - (9/9n)
Subtract the 2 fractions to get: n-9/9n
The full problem should look like this: (n-9/9n) * 9/(1+9)
To help with simplifying later, you can cancel out the 9 in the denominator of the first fraction and the 9 in the numerator of the second fraction because 9/9 = 1.
Now you have: n-9/n * 1/(1+9)
Multiply across:
Numerator: n-9 * 1 = n-9
Denominator (distribute the n): n * 1+9 = n(1+9)
Your answer is: n-9/n(1+9)

Answer: false</h3>
Work Shown:
s = false
p = true
r = false
-p = false, which is the opposite of statement p
s or -p = false or false = false
The result of an 'or' operation is false only when both parts are false; otherwise, it is true
(s or -p) or r = false or false = false
(s or -p) or r = false

Answer:
13 pints.
Step-by-step explanation:
1 US liquid quart = 2 US liquid pint
6.5 quarts = how many pints?
Cross multiplying gives:
× 2 pints = 13 pints
Answer:
Step-by-step explanation:
The equation is:
a x - c = b x + d
so we subtract b x from both sides to group the terms that contain x on the left:
a x - b x - c = d
add c to both sides to isolate the terms in x on the left:
a x - b x = d + c
extract "x" as common factor on the left:
x (a - b) = d + c
divide both sides by the quantity (a - b) to isolate the "x":
x = (d + c) / (a - b)
or:
