Sovle plzz i need help


`(k)/(4)\geq 6`


(A)k ≥ 24

(B)
`k\geq (3)/(2)`

(C)k ≥ 2

(D)
`k\geq (2)/(3)`

Answer 1

You simply have to multiply both sides by 4. In every inequality you can multiply both sides by a positive number, and this won't affect the inequality sign:

`(k)/(4) \geq 6 \iff 4\cdot (k)/(4) \geq 6\cdot 4`

And obviously the last inequality can be written as

`k \geq 24`
