Is -0.3 a rational number? is 3.14144144414444... a rational number?
Ainat [17]

I will try to make this as simple as possible.

First off, we need to know what a rational number is: A rational number is any number that can be made by dividing 2 integers. For example:

1.5 would be a rational number because 1.5 = 3/2 (3 and 2 are both integers)

With that being said, let's begin.

First off, let's start with -0.3, let's ask ourselves, can we make this number by dividing 2 integers, the answer is yes, we can, by doing \frac{-3}{10} we have the equivalent of -0.3, so now we know it's a rational number.

As for the second one, it can't be a rational number because it can't be made by dividing to integers, so the answer is:

-0.3 is a rational number, but 3.14144144414444 is not.

Hope this helped! c:

If 23 is subtracted from 8 times the number, the result is the square of 2 less than the number.
pychu [463]
I believe the answer is 116.

23-8=15
8*15=120
sqrt2=4
the number 120-4=116

that’s what i got not sure if that is correct

A jacket is on sale for 20% off the regular price. The sale price ism$50.00. What is the regular price of the jacket?
Delicious77 [7]
Lets solve for x.

 0.8x = 50. - Remember that the jacket was 80% of the original price.

Thus, divide by x.

x = 50 / 0.8
x = 62.5
