We are given the ratio of 1/2 inch: 18 miles
Multiply both sides of the ratio by 2. I'm doing this so that the "1/2" turns into "1"
So we go from this ratio
1/2 inch: 18 miles
to this ratio
1 inch: 36 miles
which means that every inch on paper represents 36 miles in real life
----------------------------------------------------------------
The question is now: if two towns are 2.5 inches apart on paper, then how far are they in real life? (note: 2.5 is the decimal form of 2 and a half)
To find out, multiply both sides by 2.5
1 inch: 36 miles
2.5*(1 inch): 2.5*(36 miles)
2.5 inches: 90 miles
--------------------------------------------------------------------------
Answer: The two towns are 90 miles apart in real life
First convert 5,280 ft. into inches.

5280 ft. equals 63360 inches.
Then you divide that by 42

If you're rounding to the nearest step then it would take 1509 steps to run 1 mile.
Answer:
The quadrilateral is Parallelogram.
Step-by-step explanation:
A quadrilateral is a four-sided regular polygon.
A parallelogram is a quadrilateral.
The opposite sides of a parallelogram are parallel and equal in length.
The opposite angles of a parallelogram are also equal.
In this case the quadrilateral is defined as follows:
- two angles that each measure 60°
- two angles that each measure 120°
- Only two of the sides have a length of 3.2 inches.
Consider the quadrilateral ABCD below.
The quadrilateral ABCD is Parallelogram.
Answer:

Step-by-step explanation:
=
=
= 
F(x) = -3x + 7
y = -3x + 7
x = -3y + 7
-3y + 7 = x
-3y = x - 7
y = -1/3x + 7/3
f^-1(x) = -1/3x + 7/3
