A quarter of the marbles are red, so there are 124/4 = 31 red marbles. The rest are blue, so there are 124 - 31 = 93 blue marbles.

Answer:

Step-by-step explanation:

The additive inverse property states that if we have a number a, then:

$a+(-a)=0$

Here, we have the equation:

$2x=542$

And we divide both sides by 2:

$2x/2=542/2$

To acquire:

$x=271$

So, we did not use the additive inverse property since we didn't add anything.

Instead, we used the division property of equality by dividing both sides by 2.

So, our answer is A.

And we're done!

This time you have to plug in the 62.10 to the P and solve for x.

I know that the new equation is now62.10=(20+0.5x)+0.15(20+0.5x)

okay so, x equal 68, the number of pages .

Combine like terms. 6y-5y is 1y, which simplifies to y. the equation is y-3=15. y=18 is the answer because you add 3 to 15
