Please help, I don’t understand these math questions?

For my homework there is a section that I do not understand.

I will give an example..

The directions are

” For the given value of a, find -a and |a| ”

“a=10.2”

What would you do with “a=10.2?

Could someone please explain this to me?

The first answer is -10.2 (Because a= 10.2. Negative a is negative 10.2. The second answer is ONLY 10.2 (positive). The absolute value of a given value is always a positive answer. It’ like asking what is the distance on the number line from zero to the given number. so the distance from 10.2 to zero is 10.2.

were doing this in school right now, and none of the current answers here are right. -a=-10.2 and the absolute value of a or the second problem is just 10.2 its not negative.

If a is equal to 10.2, then negative a would be -10.2.

and for the absolute value of a, you would do a=10.2 or a= -10.2

in a problem like that, plug in the value they give you everywhere you see an “a”

-a with a = 10.2. just plug it in:

-a = -(10.2) = -10.2

and |a| means the absolute value of a:

|a| = |10.2| = 10.2

ok to find negative a just change the sing infront of it to its oppisite and lal is absolute value so it is how many away from zero so negative a would be -10.2 and lal is 10.2

that is extremely fairly elementary, you purely would desire to comprehend it. If the shelf is 7 a million/2 ft long, you will desire to locate 3/4 of it. locate seventy 5% of seven a million/2. So first you may divide 7 a million/2 via 4, after which multiply that answer via 3.
