Let x = the number

3.5x = x + 0.5

3.5x - x = 0.5

2.5x = 0.5

x = 0.5/2.5

x = 0.2

therefore the number is 0.2

**Answer:**

72 inches

**Step-by-step explanation:**

The given relationship is ...

water = snow/12

Filling in the given information and solving for the unknown, we have ...

(6 in) = snow/12

12(6 in) = **snow = 72 in**

**It takes 72 in of winter snow to accumulate 6 in of water in the soil**.

2x - 3*(6x + 11) = 7

-16x + 33 = 7

-16x = -26

x = 13^8 or 1.625

**Answer:**

**Step-by-step explanation:**

2*5 = 10

3*5 = 15

The thing you should check is to see if the ratio of the length and width remains the same.

original length 2

============ = ====

original width 3

New length 10

========= = ====

New width 15

But 10 / 15 is the same as 2/3 so the original ratio of 2/3 is not destroyed.
