Question

What is the solution to the equation below? Round your answer to two

Answer 1

Answer:

D. x=5

The answer is x=4.50 then it is rounded off to 5. So, the answer is 5.

Step-by-step explanation:

Find the domain of the inequality:$2x-1\geq 0$

Rearrange terms to the left side of the equation:$2x\geq 1$

Divide both sides of the inequality by the coefficient of the variable:

=> $x\geq \frac{1}{2}$

The domain of the inequality is:$x\geq \frac{1}{2}$

Convert logarithm to exponential form:$2^{3}=2x-1$

Calculate the power:$8=2x-1$

Rearrange terms to the left side of the equation:$-2x= -8-1$

Calculate:$-2x=-9$

Divide both sides of the equation by the coefficient of the variable:$x=\frac{-9}{-2}$

=> $x=\frac{9}{2}$

=>$x=4.5$

Round the number: $x=4.50$

Answer: $x=4.50$

=> $x=5$
