Equation to find number: 
- 3 = 
Number's value: n = 
Step-by-step explanation:
Let n be the unknown number.
The reciprocal basically makes the number (n in this case) a fraction. So, that being said, the reciprocal of n would be .
The difference of three and the reciprocal of a number () would be - 3.
The quotient of 20 and the number (n) would be .
So, with this information we've gathered so far, we can come up with an equation to find what the number equals.
Equation: - 3 =
To find what the number equals we must solve the equation.
Answer:
So you take the 172 miles and you divide it by the 3cm that you have and that gives you 57.3 miles. And therefore 1cm would be equal to 57.3

Answer: 21 & 18
Step-by-step explanation:
Sum of two numbers is 39
Difference is 3
Let the numbers be x & y
X+y=39........equation 1
X-y=3...........equation 2
X=3+y............equation 3
Substitute equation 3 into equation 1
(3+y)+y=39
3+y+y=39
3+2y=39
2y=39-3
2y=36
Y=36/2
Y=18
Substitute for y in equation 2
X-y=3
X-18=3
X=3+18
X=21
The two numbers are 21 & 18
