We are given
Firstly, we simplify left side
Left side is
we will make all x terms together
and y terms together
we can multiply left side by using exponent rule
now, we can set them equal
Since, both sides have x,y and 8
and both are equal
so, their exponent must be equal
so, exponent of y must also be equal
we get
................Answer
Answer:
12 cm = 21.62 miles
6 cm = 11.04 miles
Step-by-step explanation:
To find the distance, set up a proportion. A proportion is two equal ratios set equal to each other. We form the ratios by using corresponding values. We write a ratio of and simplify.
We know . We know the distance on the map is 12 cm and 6 cm whish converts to 4.7 inches and 2.4 inches. We can write
and
We set them equal.
and
To solve each proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
and
