Question

If 2n + 12 = 26n, what is the value of 6n ?

8
4
3
$\frac{1}{2}$

The correct answer is: 3

We have to do algebraic manipulations to get the answer.
Explanation:
Step 1 of 2:
Given, $2 n plus 12 equals 26 n$
$rightwards double arrow 26 n minus 2 n equals 12$
$rightwards double arrow 24 n equals 12$
$rightwards double arrow n equals fraction numerator 12 over denominator 24 end fraction equals fraction numerator 1 over denominator 2 end fraction$
Step 2 of 2:
Hence, the value of $6 n equals 6 cross times fraction numerator 1 over denominator 2 end fraction equals 3$ .
Final Answer:
The value of 6n is— 3.

I = $V over R$
The formula above is Ohm's law for an electric circuit with current I, in amperes, potential difference V, in volts, and resistance R, in Ohms. A circuit has a resistance of 500 ohms, and its potential difference will be generated by n six-volt batteries that produce a total potential difference of 6n volts. If the circuit is to have a current of no more than 0.25 ampere, what is the greatest number, n, of six-volt batteries that can be used?
