Answer: 128.5km

Step-by-step explanation:

Since we are given the information that the distance by road from town A to town B is 257 km. To get 50% of the distance, we simply have to multiply the distance given by 50%. This will be:

= 50% × 257km

= 50/100 × 257km

= 0.5 × 257km

= 128.5km

Therefore, 50% of the distance is 128.5km.

Answer:5 people were in each car.

Step-by-step explanation:

Let x represent the number of people that travelled in each car.

The total number of people in the Bailey family that made the trip to the drive-in movie theater was 42.

Seven cars filled and 7 more people traveled in a truck. This means that

7x + 7 = 42

Subtracting 7 from the left hand side and the right hand side of the equation. It becomes

7x + 7 - 7 = 42 - 7

7x = 35

Dividing the left hand side and the right hand side of the equation by 7, it becomes

7x/7 = 35/7

x = 5

$\bf \left( \cfrac{3x^{\frac{3}{2}}y^3}{x^2y^{-\frac{1}{2}}} \right)^{-2}\implies \left( \cfrac{3y^3y^{\frac{1}{2}}}{x^2x^{-\frac{3}{2}}} \right)^{-2}\implies 
\left( \cfrac{3y^{3+\frac{1}{2}}}{x^{2-\frac{3}{2}}} \right)^{-2}\implies \left( \cfrac{3y^{\frac{7}{2}}}{x^{\frac{1}{2}}} \right)^{-2}
\\\\\\
\left( \cfrac{x^{\frac{1}{2}}}{3y^{\frac{7}{2}}} \right)^{+2}\implies \cfrac{x^{\frac{1}{2}\cdot 2}}{3^2y^{\frac{7}{2}\cdot 2}}\implies \cfrac{x^1}{9y^7}\implies \cfrac{x}{9y^7}$
