Question

Four more than the quotient of a number and three is at least nine

Answer 1

Answer:

Number is greater than or equal to 15.

Step-by-step explanation:

Let number be x

Quotient of number and 3 = $\frac{x}{3}$

4 more than $\frac{x}{3}$= 4+$\frac{x}{3}$

4+$\frac{x}{3}$ is at least 9

4+$\frac{x}{3}$≥9

Simplifying it ,we get

$\frac{x}{3}$≥9-4

$\frac{x}{3}$≥5

x ≥ 5(3)

x≥15

Number needs to be greater than or equal to 15  

Answer 2

$\frac{n}{3} + 4 \geq 9 \\ \frac{n}{3} + (4-4) \geq (9-4) \\ \frac{n}{3} \geq 5 \\ \frac{n}{3}(3) \geq 5(3) \\ n \geq 15$
