The steps below are presented in order to arrive to the value of k of the given equation.
First, multiply both sides of the equation by the variable k since the left-hand side of the equation has it in the denominator. This will be,
(k + 12/ k)(k) = 8(k)
Then, we simplify,
k + 12 = 8k
We then, subtract 8k to both sides of the equation,
k - 8k + 12 = 8k - 8k
Simplifying,
-7k + 12 = 0
Then, subtract 12 from both sides of the equation and divide both sides by -7. This will us the final answer of,
k = 12/7
Suppose that the number u were thinking about is x thus :
Multiply both sides by 4
Divide both sides by 3
Answer:
D. 2^7
Step-by-step explanation:
2^3 x 2^4 would equal 128. So, if you do the math for all of them:
A isn't correct because it equals 16.
B isn't correct because it equals 4096.
C isn't correct because it equals 16384.
D is correct because 2^7 is 128.
Hope this helped!
