Question

If twice a number is at least three less than four times the number, which of the following are true? Let n represent the number.

Answer 1

Explanation:

Let n represent the number

Twice the number =2n

4 times the number = 4n

Given that twice the number is atleast 3 less than four times the number

Algebraically this can be written as

2n≤4n-3

We can add 3 to both sides
`2n+3\leq 4n\\-2n         -2n\\3\leq 2n\\Or n\geq 1.5`

So n should be atleast 1.5

If n is natural number or integer then least value of n is 2.
