Step-by-step explanation:
Distance between two villages = d

First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months
10 + 7r = 45
7r = 35
r = 5
5 miles
Answer:
A. 201.6 = 11.2f
Step-by-step explanation:
we solve for each unknown to verify which equality will require the division property:
#A. 201.6 = 11.2f

Hence, division property used.
#B. 35.4=Z ÷ 3.1

Hence, multiplication property used.
#C. t/3.2=15.1

Hence, multiplication property used.
#D. 201.6 = 11.2+c

Hence, subtractionproperty used.
