Soil is the thin layer of material covering the earth's surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly. ... Therefore, most living things on land depend on soil for their existence.

X - 3/8 = 3/6 <br><br> what is x.
Anna71 [15]
X-3/8=3/6
Add 3/8 to both sides, to leave the variable alone
X= 3/6-3/8
Use common denominators-8 (3/6 is 1/2)
X= 4/8-3/8
X=1/8

Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles until he reaches a total of 26 m
sergejj [24]

Answer:

1.5x+12=26

Step-by-step explanation:  

Let x be the number of weeks that it will take Andy to reach his goal.

We have been given that Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles, so number of miles increased in x weeks will be 1.5x and total number of miles ran in x weeks will be 1.5x+12.

Since Andy wants to reach a total of 26 miles per week, so we will equate the total number of miles ran in x weeks with 26.

1.5x+12=26

Therefore, the equation 1.5x+12=26 can be used to determine x, the number of weeks that it will take Andy to reach his goal.
