$\dfrac{a}{4}-\dfrac{5}{6}=-\dfrac{1}{2}\qquad\text{multiply both sides by common denominator 12}\\\\12\cdot\dfrac{a}{4}-12\cdot\dfrac{5}{6}=12\cdot\left(-\dfrac{1}{2}\right)\\\\3\cdot a-2\cdot5=6\cdot(-1)\\\\3a-10=-6\qquad\text{add 10 to both sides}\\\\3a=4\qquad\text{divide both sides by 3}\\\\\boxed{a=\dfrac{4}{3}=1\dfrac{1}{3}}$

marta [7]

A good estimate would be $500 because if I round $26 to $25 and 22 to 20, 20x25=500

Simplify the expression by using a Double-Angle Formula or a Half-Angle Formula. <img src="https://tex.z-dn.net/?f=2%2Asin%28x%2

Tatiana [17]

Answer:

$2\sin{\frac{x}{2}}\cos{\frac{x}{2}} = \sin{x}$

Step-by-step explanation:

The double angle formula states that:

$\sin{2a} = 2\sin{a}\cos{a}$

In this question:

$2\sin{\frac{x}{2}}\cos{\frac{x}{2}}$

So

$a = \frac{x}{2}$

Then

$2\sin{\frac{x}{2}}\cos{\frac{x}{2}} = \sin{\frac{2x}{2}} = \sin{x}$
