The correct answer is Choice B.
The first step in this problem is to divide both sides by 64.
On the left side, you will have b squared.
On the right side, you will have 1/4.
Now, take the square root of both sides.
The square root of 1/4 is positive or negative 1/2.

Answer:
x=90
Step-by-step explanation:
First, it would help to make it so that the x's are not next to fractions. To do this, you can multiply all terms in the equation by 45. 45 is the closest common factor of 9 and 5, the denominators of the fractions. The answer would be;
20x+9x=2610
Then solve.
29x=2610
x=90
