During summer, when the snow melts, the water level of the Yukon River increases. If the water level of the river increased by 84 centimeters in 6 days, what is the water level increase rate in centimeters per day?

14 cm per day

Step-by-step explanation:

To find the water level increase rate in cm per day, divide 84 by 6, since it increased by 84 cm in 6 days:

84/6

= 14

So, the water level increase rate in 14 cm per day

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
