Answer:
Step-by-step explanation:
Grocery Store
12 mi / 3 cm = x / 2.5 cm Cross multiply
12 * 2.5 = 3 * x Multiply
30 = 3x Divide by 3
30/3 = x
x = 10 miles
Library
12 mi / 2 cm = x / 1.5 Cross multiply
12 * 1.5 = 2x
18 = 2x Divide by 2
18/2 = x
9 miles
The library is closer than the grocery store.
Hint: substitute 2^x by say 't': t = 2^x, then you'll have an inequality with a second order polynomial (2/t-4*t<7--> ...). In the end something like t^2 + a*t+b > 0, for some values of a and b, find the roots and get the intervals where it is satisfied.
