When an oil tank is 7/12 full, it contains 5 1/4 gallons. How many gallons does it hold when full
blondinia [14]
<h3>Answer:</h3>

The tank can hold up to 9 gallons.

Quick Review:

By doing the inverse of 7/12, 12/7, when you multiply it, you'll get a value of 1.

7/12 * 12/7 = 1

Doing the Problem:

By multiplying 5 1/4 by 12/7, you'll get the answer. But first, convert 5 1/4 into an improper fraction.

5 1/4 ---> 21/4

Okay, lets go!

21/4 * 12/7 = 252/28

<u>When reduced, this gives you the answer 9/1, or 9 gallons.</u>

Hope that helps, :)

Simplify. Assume that no denominator is equal to zero.
aivan3 [116]

Answer: FIRST OPTION.

Step-by-step explanation:

For this exercise it is important to remember a property called "Quotient of Powers property".

 By definition the Quotient of Powers property states the following:

\frac{a^m}{a^n}=a^{(m-n)}

You can observe the division of a^m and a^n. Since both have the same base "a" , you must rewrite the base and subtract the exponents "m" and "n".

In this case, you have the following expression given in the exercise:

\frac{4^{12}}{4^{5}}

Then, you need to apply the Quotient of Powers property rewriting the base 4 and subtracting the exponents 12 and 5.

Therefore, you get the following result:

=4^{(12-5)}=4^7

You can notice that it matches with the first option.

SoIve the equation a = m - n for the variable n.
vitfil [10]

Answer:

<h2>B. n = m - a</h2>

Step-by-step explanation:

a=m-n\qquad\text{subtract}\ a\ \text{from both sides}\\\\a-a=m-n-a\\\\0=m-n-a\qquad\text{add}\ n\ \text{to both sides}\\\\0+n=m-n+n-a\\\\n=m-a
