So if you're adding two negatives you move left, positive you move right, and when you have to determine a negative, and a positive you just have to see which one is the farthest from zero which the farthest one's sign is either positive, or negative. Positive to move right, and negative to move left.

Answer:

The correct answer is if you want no roots in the denominator, the correct answer is \frac{2x}{y}* \sqrt[3]{2y^{2} }

Step-by-step explanation:

The mistake is that you can't take a cube root of a square at step 3 when y^{2} is taken out.

Lapatulllka [165]
<span>MP3 player is $60
</span><span>The selling price is $105

</span><span>A classmate says that the markup is 175% because $105/$60=1.75 . Is your classmate correct?

No. IT's not correct

Original price $60
Selling price $105

$105 - $60 = $45

So

45/60 x 100 = 75%

Price is markup 75% from $60 to $105</span>
