Hi!

The answer should be third option.

$20+4j\ge 2\left(j+20\right)$

$20+4j\geq 2j+40$

$20+4j-20\geq 2j+40-20$

$4j\geq 2j+20$

$4j-2j\geq 2j+20-2j$

$2j\geq 20$

$\frac{2j}{2}\geq \frac{20}{2}$

$Answer ---> j\geq 10$

Explanation: First you had to subtract by the 20 from both sides. Then simplify it gave us 4j ≥ 2j+20. You can also subtract by the 2j from both sides. Then simplify its going to be 2j≥20. Next, you can also divide by 2 from both sides, and it gave us the answer is j≥10 is the right answer. Hope this helps! And thank you for posting at here on Brainly. And have a great day. -Charlie

What is the value of n?

melamori03 [73]

The answer for this question that needs an answer is n = 5

because 18(n-1) = 9(n+7) implies that 18n - 18 = 9n + 63 which implies that n =5 for the equation to hold true.
