We can write any number n in the form 
, since 
and 
are inverse functions, so that
The bases are the same on both sides, so the exponents must be equal.
Solve for x :
Answer:
60 miles
Step-by-step explanation:
So if 1 inch = 12 miles, you need to find 4 inches. There are multiple ways to achieve this. However ratios/proportions might be easiest.
if 1/12 = 4/x, x is the value of miles. Cross multiply so you get this:
1 4
- = - = 60 = x
12 x
If x equals 60, that means that 4 inches equals 60 miles on the map.
You could also just find an equal fraction by multiplying the top and bottom both by 4.
Just set up a proportion
(2/3)=(x/24)
cross multiply both sides
24(2)=3(x)
then solve
48=3x
x=48/3
x=16
16 is the correct answer
Divide the total cost by 4:
272 / 4 = 68
It cost $68 for 1 tire
If do the math as is shown to you will get -49.84 that I will show you its right @TTSSPony2002 so you do the math like this 3.56*-14= -49.84
