On a road map of pennsylvania, the distance from philaephia to washington d. c. is 6.8 centimeters. whatis the actual distance between the cities if the mape scale is 2 centimeters = 40 miles.

136 miles

Step-by-step explanation:

The map distance is 3.4 times 2 cm, so the road distance will be 3.4 times 40 miles, or 136 miles.

x/3-10=8

x/3=18

x=48

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
