The depth (inches) of water that accumulates in the spring soil from melted snow can be determined by dividing the cumulative winter snowfall (inches) by 12. determine the amount of winter snow that accumulates 6 inches of water in the soil.

72 inches

Step-by-step explanation:

Lets say d is the depth of the water in the soil, and s is the cumulative snowfall.

d = s / 12

If d = 6:

6 = s / 12

s = 72

A cumulative snowfall of 72 inches will melt into 6 inches of accumulated water in the spring soil.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
