Hope it helps!

Answer 2

Step-by-step explanation:

$let \: the \: number \: be \: x \\ then \: its \: twice \: = 2x \\ its \: half = \frac{x}{2} \\ according \: to \: the \: question \: \\ 2x = \frac{x}{2} + 30 \\ 2x - \frac{x}{2} = 30 \\ \frac{(4x - x)}{2} = 30 \\ \frac{3x}{2} = 30 \\ 3x = 30 \times 2 = 60 \\ x = \frac{60}{3} = 20$
