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: <u><em>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</em></u>

Dawn has 1.20 in nickels, dimes and quarters. For each nickel she has one dime and for each dime she has one quarter. How many t
kozerog [31]

Answer:

9

Step-by-step explanation:

"For each nickel, she has one dime"

That means she has the same number of nickels and dimes.

"for each dime she has one quarter"

That means she has the same number of quarters and dimes.

She has the same number of each coin.

Let's say she has x coins of each type.

The nickels are worth 0.05x; the dimes are worth 0.10x. The quarters are worth 0.25x. Altogether, the coins are worth

0.05x + 0.10x + 0.25x

We are told her coins are worth $1.20, so we set those two amounts equal and solve for x.

0.05x + 0.10x + 0.25x = 1.20

0.40x = 1.20

x = 1.20/0.40

x = 3

She has 3 coins of each type. Since there are 3 types of coins, she has 9 coins.
