The functions graphed show the snowfall, in inches, of two cities after x hours.
select each correct answer.

- smithville had a faster rate of snowfall.

- snow fell in middletown at a rate of 3 inches per hour.

- snow fell in smithville at a rate of 4 inches per hour.

- middletown had a faster rate of snowfall.

- Smithville had a faster rate of snowfall.

- Snow fell in Middletown at a rate of 3 inches per hour.

- Snow fell in Smithville at a rate of 4 inches per hour.

Step-by-step explanation:

rate is calculated as follows:

rate = (inches of snowfall)/(time in hours)

For Smithville:

rate = (10 inches)/(2.5 hours) = 4 inches per hour

For Middletown :

rate = (15 inches)/(5 hours) = 3 inches per hour

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
