Answer:
2.5 gallons
Step-by-step explanation:
Make the denominators of the fractions the same and combine them


Then simplify the fraction

Then subtract how many gallons you have from how many you want

You will need 2.5 gallons to make 3 gallons
The percentage of increase was 87.027... %
<em><u>Explanation</u></em>
The value of U.S exports to China increased from $1480 million to $2768 million.
Suppose, the percentage of increase is 
So, <u>the amount of increase</u> =
of 1480 
Thus, the equation will be......

So, the percentage of increase was 87.027... %
Answer:
12
Step-by-step explanation:
×12+8
Make use of prime factorizations:

Both terms have a common factor of
:

- - -
The second one is not true! We can write

Both terms have a common factor of
:

Since
, and
, we'd still have to show that
is a multiple of 6. This is impossible, because
and there is no multiple of 2 that can be factored out.
There are C(30, 6) = 30!/(6!*(30-6)!) = 593,775 ways to pick 6 numbers from the first 30 positive integers.
The probabilty of matching 6 randomly chosen integers is 1/593,775.
