Understanding the Absolute Value.
First, know what the absolute value is.
The absolute value is the value that determines how far the value is from 0.
For example, The absolute value of -5 is far from 0 5 units. Therefore the absolute value of -5 equals 5.
Basic Absolute Value Defines
| a | = a
- | a | = -a
| - a | = a
Back to the question. To evaluate those expressions, we use the defines of absolute value.
|-16| = 16
|-1| = 1
16-(1)
Then remove the brackets. 16 - 1 = 15
Therefore, the answer is 15.
<em>The</em><em> </em><em>answer</em><em> </em><em>above</em><em> </em><em>is</em><em> </em><em>when</em><em> </em><em>being</em><em> </em><em>subtracted</em><em> </em><em>and</em><em> </em><em>evaluated</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>16</em><em>-</em><em>1</em>
<em>Evaluating</em><em> </em><em>for</em><em> </em><em>each</em><em> </em><em>expressions</em><em> </em><em>would</em><em> </em><em>be</em>
<em>|</em><em>-</em><em>16</em><em>|</em><em> </em><em>=</em><em> </em><em>16</em>
<em>-</em><em>|</em><em>-</em><em>1</em><em>|</em><em> </em><em>=</em><em> </em><em>-</em><em>1</em>
To do this, nice it to add 3 and 5, then divide 72 by the result of sum 3 and 5. Finally multiply it by 3 and by 5 to get the result.
Lets do this
3+5=8
72:8=9 - number of rolls in 1 "unit"
9*3=27 - first group
9*5=45 - second group
Answer:
If hours is represented as h, your distance is therefore 3*h (due to that for every hour, you walk 3 miles. For example, in one hour you'd walk 3 miles, in 2 hours you'd walk 3+3=3*2=6 miles,etc.). If distance is represented by d, we get 3*h=d. Since you have to figure out the distance from the equation (that's the purpose of it!), the distance is the dependent variable. In addition, since you can't have 2 separate variables in one equation, h is the independent variable due to that you have to put a number for h in to figure out the distance
So basically the answer is A.
Step-by-step explanation:
hm
isnt is supposed to be x = -5
4x/7-6 = -20
4x/1 = -20
4x =-20
x = -5
