The number is at most 5.

Answer 1

Answer:

$z\geq 5$

The number is at least 5

Step-by-step explanation:

Let

z -----> the number

we know that

The inequality that represent this problem is

$3z+4 \leq 4z-1$

because, the phrase "no more than" is the same that "less than or equal to"

Solve for z

$4+1 \leq 4z-3z$

$5 \leq z$

Rewrite

$z\geq 5$

therefore

The number is at least 5.
