Answer:
10.48 miles.
Step-by-step explanation:
That is 4/5 * 13.1
= 10.48 miles.
64 - (3y + 8y + y) / 40 = 37
Simplify 3y + 8y + y
64 - 12y / 40 = 37
Add 12y / 40 to both sides and subtract 37
27 = 12y / 40
Multiply both sides by 40
1080 = 12y
Divide both sides by 12
90 = y
Answer:

Step-by-step explanation:
1) Add 8 to both sides.
<em />
2) Divide both sides by 2.

3) Simplify
to 4.

4) Take the cube root of both sides.
![x=\sqrt[3]{4}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B4%7D)
5) Rewrite 4 as 2².
![x=\sqrt[3]{2^2}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B2%5E2%7D)
6) Use this rule:
.
