A town's population is 57,000. About 75 people move out of the town each month. Each month, 200
people on average move into town. A nearby town has a population of 61,200. It has no one moving
in and an average of 175 people moving away every month. In about how many months will the
populations of the towns be equal? Write an equation to model the situation. Then solve the equation
and answer the question,
Which equation models the situation?
OA. 200m + 75m + 57,000 = 61,200 + 175m
OB. 200m - 75m + 61,200 = 57,000 - 175m
OC. 200m - 75m + 57,000 = 61,200 - 175m
OD. 200m + 75m + 61,200 = 57,000 + 175m

please i'm desperate i need help

the radius is 2 times the diameter.

step-by-step explanation:

54, jfvhgnjhvnjhcbnncjigjm

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

its d hope this
