Answer:

r= 7.14 (rounded to 2 decimal places)

Step-by-step explanation:

We have to solve this equation for the value of r. We will use distributive property and basic algebra to solve this.

Distributive property is a(b+c) = ab + ac

Now, the steps of solving are shown below:

$-3r-8(8r+8)=-9(-4+9r)\\-3r -64r-64=36-81r\\-67r-64=36-81r\\-67r+81r=36+64\\14r=100\\r=\frac{100}{14}\\r=7.14$

Hence, value of r is 7.14 (rounded to 2 decimal places)

Juli2301 [7.4K]

Answer:

Distance of the trail from the start to the end is $6\frac{17}{24}$ miles

Step-by-step explanation:

Distance from the start of a trail to the bird lookout point= $3\frac{7}{8}$ miles

Distance from the bird lookout point to the end of the trail = $2\frac{5}{6}$ miles

We want to find the difference of the trail from the start to the end, that is, how far is the starting point from the end point.

The distance between the start and end points

$=3\frac{7}{8}+2\frac{5}{6}\\=\frac{31}{8} +\frac{17}{6}$

$=\frac{161}{24} =6\frac{17}{24}$ miles
