Answer:

$\frac{4x - 1}{2} = x + 7 \\ 4x - 1 = 2(x + 7) \\ 4x - 1 = 2x + 14 \\ 4x - 2x = 1 + 14 \\ 2x = 15 \\ x = \frac{15}{2} \: or \: x = 7.5$

Two twin sisters, Gwen and Jackie, are both 20 years old in the year 2050. Jackie takes off on a round-trip to Vega, 25 light-ye

Contact [7]

Answer:

C. about 25 years.

Step-by-step explanation:

We have been given that two Jackie takes off on a round-trip to Vega, 25 light-years away. She travels at an average speed close to the speed of light, say, 0.9999c.

To find time it will take Jakie to reach Vega, we will divide the distance of Vega by Gwen's speed.

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

$\text{Time}=\frac{25}{0.9999}$

$\text{Time}=25.00250$

$\text{Time}\approx 25$

Therefore, it will take approximately 25 years for Jakie to reach Vega and option C is the correct choice.
