Answer:
2
Step-by-step explanation:
|a+x|/2 − |a−x|/2 , if a=−2; x=−6
Evaluate this expression
Simply plug in the numbers
| -2 + -6 | /2   -   |-2 - -6|/2
|-8| /2  -   |4|/2
4 - 2

Answer:
0.6x+y=24.6
Step-by-step explanation:
y-y1=m(x-x1)
y-24=-0.6(x-1)
y=-0.6x+0.6+24
y=-0.6x+24.6
y-(-0.6x)=24.6
y+0.6x=24.6
0.6x+y=24.6

Answer:
SSS
Step-by-step explanation:
REM and DME share a side. This side is of course congruent.
In addition, sides RM and ED are marked as congruent, as are RE and MD.
All three corresponding sides of each triangle are congruent, which proves the triangles' congruency. 
No information is given about the angles in these triangles, so none of the other theorem answer choices are valid.
Please mark brainliest! :)
 
        
                    
             
        
        
        
Age of Jen is 13.6 years old
<em><u>Solution:</u></em>
Let "x" be the age of Jack and "y" be the age of Jen
Given that This Christmas, your brother Jack will be 2 years from being twice as old as your sister Jen
The above sentence can be written mathematically as:
Jack age + 2 = twice of age of Jen

The sum of Jacks age and three times Jen's age is 66
Jack age + three times Jen age = 66
x + 3y = 66 ---- eqn 2
Substitute eqn 1 in eqn 2
2y - 2 + 3y = 66
5y - 2 = 66
5y = 68
<h3>y = 13.6</h3>
Thus age of Jen is 13.6 years old
