Last year during the hurricane season, the amount of rain that fell on the Texas Gulf Coast in October was 14 inches, which was 3 1/2 times more than the rainfall during September of the same year. How much rain fell during the month of September?

4in

Step-by-step explanation:

Given

Amount of rain that fell in October = 14in

If this value is 3 1/2times amount of rain that fell in September, we can express it mathematically as;

3 1/2 of September = 14

7/2 of x = 14

x is the amount of rain that fell in September

From the expression

7x/2 = 14

Cross multiply

7x = 14×2

7x = 28

Divide both sides by 7

7x/7 = 28/7

x = 4in

Hence the amount of rain that fell in September is 4in

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
