Lol I’m horrible at math I’m sorry
Ratling [72]

Okay so first we see the left half is in between "| |" and that means absolute value. That means whatever number is between those lines, you make positive. Now we just plug in the numbers from the choices and see which ones apply.

|27 - 7.5| ≤ 17

|19.5| ≤ 17

19.5 ≤ 17

False. Choice A is not the answer.

|20 - 7.5| ≤ 17

|12.5| ≤ 17

12.5 ≤ 17

True. Choice B is one of the answers.

|(-9) - 7.5| ≤ 17

|-16.5| ≤ 17

16.5 ≤ 17

True. Choice C is also an answer.

The two that apply are B and C.

Hope that helps!

What is 2/3 of 800 dollars
omeli [17]
2/3 of 800

The word 'of' generally means multiply, so then

(2/3) * 800

800 is like 800/1, the fraction, and when multiplying fractions we multiply the top of the first and the second together, and multiply the bottom of the first and second together (numerator, denominator).

\frac{2}{3} * \frac{800}{1}
=\frac{1600}{3}
=533.333333333333

You don't really need the 800/1, but that might make it more clear exactly what's happening.

Edit: So I'm not sure if it's just me or that LaTeX formatting actually doesn't render. If not,

(2\3)*(800/1) = 1600/3 = 533.333333
