Answer:
A
Step-by-step explanation:
Given
20 - || - 13 | + 17 |
Note the absolute value function always returns a positive value, that is
| - a | = | + a | = a, thus
= 20 - | | - 13 |+ 17 |
= 20 - | 13 + 17 |
= 20 - | 30 |
= 20 - 30
= - 10 → A
Always start with what’s in the parentheses:)
I believe the answer is 2783 for 1 a - either
First set it up like this:

<span>then add a zero on to the 18 and a decimal point like this: </span>

then solve for 180/32 and add a decimal in the same location that it is in the 18.0 Hope this helps!
