Answer:

For example: 0=1 This is false because we know zero can't equal one. Therefore we can conclude that the problem has no solution. You can solve this as you would any other equation. 13x−5(x−4)=8x+513x−5x+20=8x+58x+20=8x+58x−8x+20=8x−8x+520=5 We see this is a false statement because 20 does not equal 5.

Daniel has a set off green,blue, and red the red marblesmmake up exactly 1halfs of the set the set has 2 blue marble the number

Blizzard [7]

Answer:

There are 12 marbles in Daniel's set.

Step-by-step explanation:

Given:

Daniel has a set off green,blue and red.

The red marbles make up exactly half of the set.

The set has 2 blue marbles.

The green marbles in set are as twice of the blue marbles in set.

Now, to find the number of marbles in Daniel's set.

Let the number of marbles in Daniel set be $x.$

So, the red marbles = $\frac{1}{2}\ of\ x$ $=\frac{x}{2}$

Blue marbles = 2.

And the green marbles = $2\times 2$ $=4.$

According to question:

$x=\frac{x}{2} +2+4$

$x=\frac{x}{2} +6$

$x=\frac{x+12}{2}$

Multiplying both sides by 2 we get:

$2x=x+12$

Subtracting both sides by $x$ we get:

$x=12.$

Therefore, there are 12 marbles in Daniel's set.
