The rain caused the river to rise a total of 6 and 2/3 inches. the river was rising at an average of 2/3 of an inch each hour. how many hours did it rain? (must be a whole number) (there is a ratio) (2/3 divided by 1) and (6 and 2/3 divided by what? )

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !

i think its 7.6

if so your welcome
