A scale drawn on the map shows that 1 inch represents 10 miles. If two cities are 3.5 inches apart on the map, what is the distance between them in real life? A. 35 miles B. 45 miles C. 55 miles D. 25 miles

a 35

Step-by-step explanation:

1/10 = 3.5/x

cross multiply and solve

or just do 10 x 3.5 right away

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

109 is the nearest whole number/final answer! : )
