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: here u go
Step-by-step explanation:
Answer:
Solution: 
, 3.5, -15, 5
Not a solution: 129 and 
Step-by-step explanation:
20 ≥ 5 + 3x
3x + 5 ≤ 20
3x ≤ 20 - 5
3x ≤ 15
x ≤ 5
x must be LESS than or EQUAL to 5
Answer:
is it asking for linear functions
The two ways to find the ratio of the length is to turn the inches into feet or the feet into inches
So the answer can be solved like this:
1/36ft to 1/4ft which is 9:1 (blueprint size to actual size)
or
1/3in to 3in which is also 9:1 (blueprint size to actual size)
