The original price was $300. It is sold for $387. What percentage was the original price

The original percentage was 100% when it was purchased. But, by the time it was sold it had increased in value to 387.

So, the percentage increase from 300 to 387 is,

387/300=1.29 - 1=.29 X100=29% increase

If you want to know what percent of 387 is 300, then just do the reverse, i.e.,

300/387=.7716 X100=77.16%

-83/100

One way of doing it is to multiply:

128 X 25 X 7=22,400

1.77245385091

Here's a good resource that explains this :  http://www.purplemath.com/modules/sqrquad.htm

sqrt(9/16)  = 3/4

1/2+7x/10=13/20       multiply through by the common denominator of 2, 10 and 20, i.e., (20)

10 + 14x  = 13           subtract 10 from both sides

14x  = 3                     divide both sides by 14

x = 3/14

That it's a mouthful to say.

(1 + 1/4) * -(2 + 3/5) =

(5/4) * (-13/5)  =

(-13/4) * (5/5)  =

(-13/4) * (1)  =

-13/4

Not EVERYONE finds it boring but those who find it boring might find it boring due to all the numbers, pointless equations, and numerous graphs depicting various statistics and percents. The work can get quite difficult and confusing but it helps you in real life even if you find it excruciatingly boring.

This is just a notational convention

ae(+/-)N    just means    a x 10^(+/-)N

The answer to 5/7+15 -6 is 9.71428571429 is you solve it exactly the way you have it.

When solving you have to keep in mind the order of operations and the signs themselves or you may not get the correct answer.

Technically speaking it can be 2 but also 11.

If you have one dollar and someone gives you another, you now have two dollars total but visually if you have a single one(1) and then add another you now have two number ones but the new number would be 11.

If we have this :

(-9)⁴    the answer is  6561

If we have this :

-9⁴   the answer is -6561

36x + 9     is all we can do.....these are unlike terms, so we can't add them as such

This is a straight line......here's the graph.........https://www.desmos.com/calculator/0juzyo6k8e

yes and 1 with 100 0's is 1 googol

-5x+6

Dividing fractions is as easy as pi; flip the second and multiply

Because it isn't?
