Answer:

B. 4

Step-by-step explanation:

Create an equation:

80 = 18x+8

Solve for x by subtracting both sides by 8:

80-8 = 18x+8-8

72 = 18x

Divide both sides by 18:

72/18 = 18x/18

4 = x

In maths, Distance is described as the quantity of space between two points, and further calculation can be defined as follows:

Given Expression:

$5x + 2 = 30\\\\2(x + 5) = 30\\\\5(x + 2) = 30\\\\2x + 5 = 30$

To find:

distance=?

Solution:

$5\ days\ \begin{cases} & \text{ if } \text{before school 2 miles} \\ & \text{ if } \text{after school x miles} \end{cases}$

$\therefore 5(x+2)=30\\\\$

$\bold{5(x+2)=30}\\\\\bold{5x+10=30}\\\\\bold{5x=30-10}\\\\\bold{5x=20}\\\\$

$\bold{x=\frac{20}{4} }\\\\\bold{x=4}$

Therefore, the final answer is "4 miles".
